摘要:
A ceramic heater is constructed by embedding a heat-generator in a base body made of ceramics. The heat-generator has a recess in a surface thereof, the ceramics being inside the recess. Even if a great thermal stress is developed due to a difference in thermal expansion between the heat-generator and the base body, by the recess inside which the ceramics that forms the base body exists, occurrence of a gap between the heat-generator and the base body, as well as appearance of cracks in the base body, can be prevented even in the direction of the length of the heat-generator in which the thermal stress is applied heavily.
