テーパー状に形成されていることを特徴とするセ
ラミツクグローブプラグ。 On the outside of the rod-shaped ceramic heater, which is made by embedding heat-generating wires of high-melting point metal in ceramic powder and sintering them, a metal outer cylinder is joined to the tip of the inner cavity of the mounting bracket, exposing the heat-generating tip of the heater. What is claimed is: 1. A ceramic glow plug fitted with a metal outer cylinder, characterized in that a tip portion of the metal outer cylinder protruding from a mounting bracket is formed into a tapered shape.
