A heat receiving member of a heat receiving device includes a coolant passage comprising a bag formed of a flexible sheet made up of a thermally stable, flexible plastic material and a metal film having high heat conductivity. In the coolant passage flows a coolant having an anti-corrosion property. A heat generating member including a main body and a terminal portion is supported by an adapter fitted in an opening formed in the flexible sheet. The main body of the heat generating member comes into direct contact with the coolant flowing in the coolant passage. Since the heat from the heat generating member is directly transferred to the coolant, the heat transfer path between the heat generating member and the coolant becomes shorter. Therefore, the heat resistance is reduced, so that the heat receiving efficiency is extremely high.
