Zusammenfassung:	To provide a gasket for an ignition plug which enables improvement of airtightness between a combustion chamber of an internal combustion engine and the outside.SOLUTION: A gasket for an ignition plug is used to attach an ignition plug to a wall part in a cylinder head of an internal combustion engine. The gasket for the ignition plug includes: an annular body part 23; protruding parts 25 protruding from the body part to the radial inner side; and first extension parts 41A which extend from the protruding parts to the side of a specific surface 22 that is a wall part side surface of the body part in an axial direction of the body part. Each first extension part separates from the body part except a connection part connected to the protruding part.SELECTED DRAWING: Figure 9 【課題】内燃機関の燃焼室と外部との間の気密性を向上させることのできる点火プラグ用ガスケットを提供する。【解決手段】点火プラグ用ガスケットは、内燃機関のシリンダヘッドにおける壁部に点火プラグを取り付ける際に用いられる。点火プラグ用ガスケットは、環状の本体部２３と、本体部から径方向の内側に突出した複数の凸部２５と、各凸部から、本体部の軸方向において本体部の壁部側の面である特定面２２の側に延びる複数の第１延長部４１Ａと、を備える。第１延長部は、凸部との接続部を除いて本体部から分離されている。【選択図】図９
