A ceramic base body (4), 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 (4a), and a mixed-material layer (2) disposed between two ceramic layers (4a), the mixed-material layer (2) being formed of a mixture of a ceramic material and a metal material. Between the ceramic layer (4a) and the mixed-material layer (2), a heat-generating resistor (3) 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 (3) is suppressed by the mixed-material layer (2), wherefore the adverse effect of the radiation on surrounding electronic devices can be reduced. |
