PROBLEM TO BE SOLVED: To provide a cooler with long durability, good cooling efficiency, and less failures. SOLUTION: A liquid receiving tank 1 storing a liquid medium, a medium heater 3 heating and evaporating the liquid medium from the liquid receiving tank 3, a condenser 11 condensing and liquidizing the medium vapor generated from the medium heater 3, and an evaporating cooler 13 evaporating the condensed and liquidized medium and absorbing peripheral heats are interposed in a medium circulation path 2. A face-like heating element 6 provided with heating layers 61B, 62B, 63B on an outer face and/or an inner face of a base 6A is wound around the outer periphery of the medium heater 3. The face-like heating element 6 with such a constitution has large mechanical strength and good heating efficiency. COPYRIGHT: (C)2003,JPO
