囲第１項記載の沿面放電型プラグ。[Claims for Utility Model Registration] (1) A discharging end of a center electrode that abuts against the conical step surface of the inner cavity of the main metal fitting to house and fix an insulator, and is held in the shaft hole of the insulator. In a creeping discharge type plug in which an annular spark gap is formed along the end face of the insulator firing part between the periphery and the inner wall of the firing part of the metal shell opposing the periphery, heat is generated inside the insulator near the end face of the insulator firing part. A creeping discharge type plug characterized by a buried body. (2) A spatial discharge gap in which the spark gap is formed by reducing the diameter of the tip of the center electrode and providing an annular space between it and the insulator shaft hole; and a creeping discharge gap along the end surface of the insulator firing part. A creeping discharge type plug according to claim 1 of the utility model registration claim.
