プラグ。The heating element exposed at the tip of the mounting bracket is a ceramic heater made by embedding a heating wire of a high melting point metal in ceramic powder and sintering it, and both ends of the heating wire of the ceramic heater are insulated. In the two-wire ceramic glow plug, the ceramic heater has a central electrode portion with one end of the heating wire exposed on the outer peripheral surface of the rear end portion; A connection structure is provided in which an outer electrode portion is provided on the outer circumferential surface of the heater body that is close to and separated from the rear end portion, and the other end of the heating wire is exposed, and lead wires are joined to both electrode portions, respectively. 1. A two-wire ceramic glow plug characterized in that it has an insulation reinforced structure in which the entire electrical connection part in the inner cavity of these fittings is covered with a heat-shrinkable resin and is heat-shrinked.
