1. An image capturing apparatus comprising:
an image sensor unit that includes an image sensor board on which an image sensor is mounted;
a first drive mechanism that drives the image sensor unit in a first direction orthogonal to an optical axis of the image sensor;
a second drive mechanism that drives the image sensor unit in a second direction which is orthogonal to the optical axis and different from the first direction;
a unit cooling duct disposed on an opposite side of the image sensor board to a surface on which the image sensor is mounted, such that the unit cooling duct is opposed to the image sensor board, so as to allow air for cooling the image sensor unit to pass therethrough; and
a heat conduction member that is connected to the image sensor unit and the unit cooling duct, and transfers heat from the image sensor unit to the unit cooling duct,
wherein the unit cooling duct has an air suction port for suctioning the air and an air discharge port for discharging the air,
wherein when viewed from the optical axis direction, the first drive mechanism, the second drive mechanism, the air suction port, and the air discharge port are in a positional relation not overlapping one another around the image sensor, and
wherein the heat conduction member is a flexible heat conduction member that is extendable/contractable.
