A heat radiating structure of a digital camera includes an optical system holder which holds an image-forming optical system; an image pickup device supported by the optical system holder; an outer casing which constitutes an external body of the digital camera which surrounds the optical system holder, the outer casing having a through-hole which communicatively connects the inside of the outer casing with the outside thereof; an external radiating member installed in the through-hole, being made of a material having a thermal conductivity higher than that of the outer casing; a heat radiating plate, one end of which is connected to the image pickup device and another end of which extends into a space between the external radiating member and the optical system holder; and a heat transfer member via which the heat radiating plate and the external radiating member are connected to each other.
