This invention has its object to provide a ceramic heater provided at low cost without being compromised in its performance, with the result that a ceramic heater equivalent to the conventional product in performance characteristics can be manufactured at reduced cost. A ceramic heater comprising a core, an insulation sheet covering said core and a resistance heating element of high-melting metal as embedded between said core and insulation sheet, a high-temperature part of said resistance heating element, the operating temperature of which reaches 300 DEG C or higher, comprises a high-melting metal supplemented with Re or Mo. <IMAGE>
