1. A voltage detection unit comprising:
a voltage detection terminal having a plate-shape and having a connection portion configured to be electrically connected to a detection target;
a housing having a plate shape and having an accommodating concave portion configured to accommodate the voltage detection terminal; and
a cover configured to be attached to the housing by being moved from a first side toward a second side along a first direction and to cover the accommodating concave portion,
wherein the cover is configured to be locked to the housing at a temporary locking position at which the cover covers only a part of the accommodating concave portion such that the connection portion is exposed and at a final locking position at which the cover covers an entirety of the accommodating concave portion,
wherein the cover includes: a main body portion configured to, when the cover is at the final locking position, cover the accommodating concave portion and including a locking portion provided on a third side in a second direction being perpendicular to the first direction and being a longitudinal direction of the voltage detection unit; and a locking piece provided on a fourth side opposite to the third side along the second direction and extending from the main body portion toward the second side along the first direction,
wherein the housing includes: a locked portion provided on the third side and configured to be locked to the locking portion; a locking hole provided on the fourth side and configured to accommodate the locking piece; and an extending portion formed by a part of an edge of the locking hole, the part extending toward the first side along the first direction, and
wherein a distal end of the locking piece on the second side is accommodated in the locking hole when the cover is at the temporary locking position.
