コイル巻線ピツチが密な第１の密な部分を設け、
この第１の密な部分から陽電極取出し金具側へコ
イル巻線ピツチが粗な部分を介して第２の密な部
分を設け、これを陽極端子側へ接続すると共に、
前記第１の密な部分の他端を陰極端子側へ接続す
ると共に、これら第１の密な部分及び第２の密な
部分ともにグロープラグ先端の前記焼結体固定用
金属環より先端側に位置するようにしたことを特
徴とする急速昇温―温度飽和型グロープラグ。 A coiled heat-generating resistance wire is installed inside the rod-shaped ceramic sintered body, an anode extraction fitting is provided at the base end of the ceramic sintered body, and the intermediate part is fixed to a metal ring.The temperature is rapidly raised when the engine is started, and then saturated to a constant temperature. This is a rapid temperature rise-temperature saturation type glow plug designed to increase the temperature, and the heating resistance wire at the tip of the ceramic sintered body is provided with a first dense portion where the coil winding pitch is dense,
A second dense portion is provided from this first dense portion to the anode extraction metal fitting side via a portion where the coil winding pitch is coarse, and this is connected to the anode terminal side,
The other end of the first dense portion is connected to the cathode terminal side, and both the first dense portion and the second dense portion are disposed closer to the tip side than the metal ring for fixing the sintered body at the tip of the glow plug. A rapid temperature rise-temperature saturation type glow plug that is characterized by being positioned in the same position.
