1. An imaging device comprising:
a heat generating source;
a heat radiating plate that cools the heat generating source;
a thermoelectric element that includes a heat absorbing surface in contact with the heat radiating plate and a heat radiating surface different from the heat absorbing surface, and receives supply of electric power to discharge heat absorbed by the heat absorbing surface from the heat radiating surface;
a first heat sink that is in contact with the heat radiating surface of the thermoelectric element and is spaced apart from the heat radiating plate;
a second heat sink that is in contact with the heat radiating plate; and a substrate on which the heat generating source is mounted, wherein
the substrate includes a through hole, and
the heat radiating plate includes, on a surface facing the substrate, a convex portion that enters the through hole of the substrate to be in contact with the heat generating source.
