Abstract

　汚損時に接地電極と中心電極や絶縁碍子との間にて起こり得る横飛火の発生を確実に防止することができるスパークプラグおよびその製造方法を提供する。 接地電極（３０）の基部（３２）の端面（３５）を全面にわたって主体金具（５０）の先端構成面（５７）と接触させた状態で、接地電極（３０）と主体金具（５０）とが溶接等により接合される。この接地電極（３０）は軸線（Ｏ）方向に沿って前方へ延びる延伸部（３６）を有しており、屈曲部（３７）を介して、先端部（３１）が中心電極（２０）の先端部（２２）に接合された貴金属チップ（９０）に対向しており、両者間で火花放電間隙（Ｇ）が形成されている。そして接地電極（３０）の屈曲部（３７）における内面（３３）に接触する半径１．２ｍｍの仮想球体（Ｑ）が中心電極（２０）や絶縁碍子（１０）とは接触しない（つまりその大きさの仮想球体（Ｑ）を配置可能となる）十分な大きさの空隙部分（懐）を有する構成となっている。
