PURPOSE:To enable a good portability, an easy movability and a facilitated use to be realized by mounting both a Joule heating unit element and a thermoelectric effect element to a heating medium member brought into contact with an electronic part. CONSTITUTION:A heating medium member 5 is formed from a metal piece, for example, aluminum or the like with a high thermal conductivity. The metal piece is processed to such a configuration as to be able to be brought into close contact with an electronic part 11. A temperature sensor 4 is buried in the heating medium member 5. A plurality of thermoelectric effect elements 2 and a plurality of resistance heating elements 3 are mounted to the heating medium member 5 while both the elements checkedly entering into each other. The heating medium member 5 is adapted to be quickly cooled or heated to a given preset temperature through a controller. Thus, an easy portability and a facilitated use are realized and only a target electronic part can be efficiently heated or cooled.
