１項記載の自己制御型セラミツクグロープラグ。[Scope of Claim for Utility Model Registration] (1) A self-control ceramic glow plug in which a resistor connected in series with a ceramic heater is inserted into the inner cavity of a mounting bracket, including the center shaft and both end connections with the ceramic heater. A ceramic resistor having a resistor coil embedded in a ceramic sintered body is joined with one end surface of the ceramic resistor in contact with the rear end surface of the heater in the inner cavity of a connecting metal pipe, and the joined portion and other parts are bonded. A self-regulating ceramic glow plug characterized in that the inner cavity of the mounting bracket is filled with a heat-resistant insulator so as to be buried including the connection between the end and the center shaft. (2) The self-regulating ceramic glow plug according to claim 1, wherein the heat-resistant insulator is a powder of magnesia or the like. (3) The self-regulating ceramic glow plug according to claim 1, wherein the heat-resistant insulator is filled by melting glass.
