- the resistance heating part 1210 may be a PTC heater using barium titanate (BaTiO 3 ) having PTC characteristics as a resistor. In such a case, the resistance heating part 1210 can set the Curie temperature of barium titanate to 350.degree.

- FIG. 4 is a graph diagram schematically showing the relationship between the density of the carbon porous body and the electrical resistance value.
- the electrical resistance of the carbon porous body abruptly decreases when the carbon density is 0.3 g/cm 3 or more. This is because the increased density facilitates the formation of a carbon network, thereby facilitating the flow of current. Therefore, when the density of carbon added to barium titanate is 0.3 g/cm 3 or more, the electrical resistance of carbon becomes lower than the electrical resistance of barium titanate, so that current does not flow through carbon alone. It may get lost. In such a case, there is a possibility that the resistance heating part 1210 will not function as a PTC heater because current will not flow through the barium titanate having PTC characteristics. Therefore, the density of carbon added to barium titanate is preferably controlled to less than 0.3 g/cm 3 .
