成されたことを特徴とするグロープラグ。 A heating element whose one end is connected to the bottom tip in a bottomed metal tube formed by closing one end of a metal tube, and a resistor with a large positive resistance temperature coefficient for current control connected in series to the other end of the heating element. In the glow plug, the heating element is made of a metal having a negative temperature coefficient of resistance, and is embedded in the metal tube through insulating powder, with the tip side of the metal tube protruding from the end surface of the mounting fitting. A glow plug characterized by being formed from a wire-wound coil of a resistive material.
