Abstract

　本発明のスパークプラグは、主体金具に形成される取付ねじのＪＩＳ規格に準拠した呼び径がＭ１２以下である小径のスパークプラグとして作製され、接地電極は、一端部側から他端部側へ向かって延びる第１部材の外面上に、少なくとも１つ以上の第ｉ部材（但し、ｉ＝２，３，４，５である。）をそれぞれ層状に被覆したものであり、他端部の主体金具の先端面からの突出長さが４．５ｍｍ以上であり、且つ一端部と他端部との間に自身を２．３ｍｍ以下の曲率半径で屈曲させた屈曲部を有し、突出長さが０．５ｍｍ以上、断面積が０．２０～１．１３ｍｍ2の大きさの電極チップが他端部において中心電極の先端部と対向する位置に接合されている。このとき、式（１）によって表される接地電極の２０°Cにおける合成熱伝導率Ｘを３５Ｗ／（ｍ・Ｋ）以上となるように接地電極を構成する材料を選択すれば、熱引き性能を向上させ、疲労強度の低下を抑制することができる。
