An image pickup apparatus that does not give a user, who grips an apparatus body with his/her hand when he/she uses the imaging apparatus or the electronic device, a sense of discomfort due to a heat, and that can efficiently diffuse heat generated from a heat source inside the apparatus body to suppress a local temperature rise inside the apparatus body. An image pickup apparatus comprises an outer cover that forms an exterior of a device body, the device body having a grip at one end thereof and having a heat source therein. A first thermal conductive path from a first circuit unit to a first heat storage member via a first heat conductive member and a second thermal conductive path from a second circuit unit to a second heat storage member via the second heat conductive member are separated from each other.
