Abstract:
A ceramic heater produced by a process comprising the steps of:coating an entire surface of a pair of lead-out wires, the entire surface extending from a take-out wire to a U-shaped heating resistor, with a metal;connecting one-side ends of said pair of lead-out wires comprising tungsten to both ends of the U-shaped heating resistor to obtain a heater main body;embedding said heater main body in a ceramic powder comprising at least one of Si.sub.3 N.sub.4, Sialon, and AlN; andhot-pressing said powder containing said heater main body embedded therein to sinter said powder to thereby obtain a sinter in which the other ends of said lead-out wires are exposed on a surface of said resultant sinter.
