Of course, the lower electrode is elastically supported by a plurality of leg pieces, and the PTC heater is pressed by a protrusion provided on the contact terminal of the lower electrode, and further serves as the upper electrode. Since the PTC heater is directly sandwiched between the heat sink and the heat sink, the heat sink is directly heated by the PTC heater, and the heat sink is coated on the heat sink. Since the temperature of the resin lid rises and the object to be heated placed on the lid is heated by this temperature, the object to be heated can always be kept at a constant temperature. Become. Furthermore, since a thermistor or the like for temperature control is not required unlike the conventional ceramic heater, the number of parts can be reduced, and it contributes to cost reduction. The PTC heater part is covered with the synthetic resin lid. Since it is coated, it is an invention that has a significant effect such as an improvement in the aesthetic sense of the appearance.
