1. A heat exchanger for heat exchange between a first fluid and a second fluid, the heat exchanger comprising:
a body part which is an additive manufactured body and includes at least one first passage through which the first fluid flows and at least one second passage through which the second fluid flows; and
a covering part attached to the body part,
wherein the body part has at least one first opening portion of the at least one first passage and at least one second opening portion of the at least one second passage, and the covering part is attached to the body part so as to cover exposure of the at least one first opening portion and the at least one second opening portion,
wherein the body part includes:
a first header passage through which the first fluid flows;
at least one first distribution passage connecting the first header passage and the at least one first passage;
a second header passage through which the second fluid flows; and
at least one second distribution, passage connecting the second header passage and the at least one second passage; and
a first fixed wall and a second fixed wall fixed to the body part,
wherein the at least one first opening portion is at least one opening portion of the at least one first distribution passage in the first fixed wall, the at least one second opening portion is at least one opening portion of the at least one second distribution passage in the second fixed wall,
wherein the heat exchanger includes a housing part into which the body part can be inserted,
wherein the first separation wall and the second separation wall are provided to the housing part, and
wherein when the body part is inserted into the housing part, the first separation wall and the second separation wall are attached to the first fixed wall and the second fixed wall, respectively.

5. A heat exchanger for heat exchange between a first fluid and a second fluid, the heat exchanger comprising:
a body part which is an additive manufactured body and includes at least one first passage through which the first fluid flows and at least one second passage through which the second fluid flows; and
a covering part attached to the body part,
wherein the body part has at least one first opening portion of the at lest one first passage and at least one second opening portion of the at lest one second passage, and the covering part is attached to the body part so as to cover exposure of the at least one first opening portion and the at least one second opening portion,
wherein the covering part includes a lid member attached to the body part so as to cover the at least one first opening portion and the at least one second opening portion,
wherein the covering part is attached to the body part via seal member between the covering part and the body part,
wherein the seal member includes:
an inner seal member disposed so as to surround at least one of the at least one first opening portion or the at least one second opening portion with the covering part being attached to the body part, and
an outer seal member disposed on an opposite side of the inner seal member from the at least one of the at least one first opening portion or the at least one second opening portion, and
wherein the outer seal member has notch with a distance in a direction of extension of the outer seal member,
wherein the body part has a storage part communicating with the notch and capable of storing the first fluid or the second fluid,
wherein the heat exchanger comprises a detection part for detecting inflow of the first fluid or the second fluid into the storage part,
wherein the heat exchanger comprises:
a first open/close valve for supplying the first fluid to the at least one first passage or stopping the supply of the first fluid;
a second open/close valve for supplying the second fluid to the at least one second passage or stopping the supply of the second fluid; and
a control part electrically connected to the detection part, the first open/close valve, and the second open/close valve, and
wherein the control part closes the first open/close valve and the second open/close valve when a signal indicating detection of inflow of the first fluid or the second fluid into the storage part is transmitted from the detection part.

9. A heat exchanger for heat exchange between a first fluid and a second fluid, the heat exchanger comprising:
a body part which is an additive manufactured body and includes at least one first passage through which the first fluid flows and at least one second passage through which the second fluid flows; and
a covering part attached to the body part,
wherein the body part has at least one first opening portion of the at least one first passage and at least one second opening portion of the at lest one second passage, and the covering part is attached to the body part so as to cover exposure of the at least one first opening portion and the at least one second opening portion,
wherein the covering part includes a lid member attached to the body part so as to cover the at least one first opening portion and the at least one second opening portion,
wherein the first passage and the second passage that are adjacent to each other are separated by a partition wall,
wherein the lid member is provided with a seal member configured to be deformable by abutting on an end portion of the partition wall when the lid member is attached to the body part,
wherein the end portion of the partition wall has a seal groove portion recessed with respect to the end portion,
wherein the seal groove portion is defined by two inclined surfaces connected to each other at a bottom portion of the seal groove portion,
wherein the seal member includes a deformable abutting portion, and
wherein the abutting portion is inserted in the seal groove portion and abuts on each of the two inclined surfaces.
