Abstract
A ceramic base body, which is a ceramic heater which suppresses noise radiation and thus has little adverse effect on surrounding electronic devices, includes a plurality of ceramic layers, and a mixed-material layer disposed between two ceramic layers, the mixed-material layer being formed of a mixture of a ceramic material and a metal material. Between the ceramic layer and the mixed-material layer, a heat-generating resistor which generates heat by a passage of electric current therethrough is disposed. Radiation of a high-frequency component generated by the passage of electric current through the heat-generating resistor is suppressed by the mixed-material layer, wherefore the adverse effect of the radiation on surrounding electronic devices can be reduced.
