An endoscope apparatus includes an insertion portion inserted into a body, an optical member arranged exposed from an outside surface at a distal end of the insertion portion, an objective optical system that condenses light impinged from the optical member, an electronic image pickup circuit that photoelectrically converts the light condensed by the objective optical system, a heat absorbing section arranged in the vicinity of the electronic image pickup circuit for absorbing heat generated from the electronic image pickup circuit, a heat transfer section extending toward the optical member side for transferring heat of the heat absorbing section, a heat radiation section arranged in the vicinity of the optical member for radiating heat transferred by the heat transfer section to the optical member, and a heat transfer member that is formed by patterning a metal foil on an insulating, flexible film member and includes the heat absorbing section, the heat transfer section and the heat radiation section.
