ABSTRACT:
There is provided a uniform heating structure in the heating device formed in the shape of a hollow block made of a heat-resistant metal, in which the surface of the heating device is used as a heat transfer surface, and a high thermal-conductivity material with a thermal conductivity higher than the thermal conductivity of the metal is located adjacent to the heat transfer surface in such a manner that heat can be transferred to the heat transfer surface.
