１項記載のデイーゼルエンジン用グロープラグ。[Claims for Utility Model Registration] (1) A rod-shaped ceramic heater is provided which is held at the tip of a hollow holder with one end protruding outside. It is constructed by integrally forming a pair of lead parts extending parallel to the rear from a conductive ceramic material, and the outer surfaces of both lead parts are bonded and held to the tip of the holder via an insulating layer. The glow plug for a diesel engine is further characterized in that the one lead portion is grounded to the holder side through a cutout formed in a part of the insulating layer. (2) Ceramic heaters are integrally formed of ceramic material whose insulating and conductive properties can be selected by adjusting the amount of titanium nitride added to β-sialon or sialon with a mixed phase of α and β. A glow plug for a diesel engine according to claim 1 of the utility model registration claim.
