1. An image pickup apparatus comprising:
a housing with an opening, the housing being made of metal;
a first circuit board mounted with an image sensor;
a second circuit board mounted with an electric element and is placed opposite to the first circuit board;
a heat radiating sheet that contacts the image sensor and the housing; and
a flexible member placed between and contacting the heat radiating sheet and the second circuit board,
wherein the flexible member includes a gel member,
wherein there is an area around the gel member that allows the gel member to move or deform,
wherein a first area of the heat radiating sheet contacts a back surface of the image sensor, and
wherein a second area of the heat radiating sheet is folded with respect to the first area, disposed outside the housing via the opening of the housing, contacts an outer surface of the housing, and is fixed to the outer surface of the housing by using a fixing member.
