付金具に棒状外側電極を突設し、該外側電極の先端部を
折り曲げて中心電極の先端面と対向させ、放電間隙を形
成させる点火栓において、前記中心電極の先端面に、前
記外側電極の折り曲げ部と同じ方向に所定の間隔で２本

ことを特徴とする点火栓。A rod-shaped outer electrode is protruded from a cylindrical mounting bracket that is fitted around the rod-shaped center electrode via an insulator, and the tip of the outer electrode is bent to face the tip surface of the center electrode to form a discharge gap. In the spark plug, two protrusions are formed on the tip surface of the center electrode at a predetermined interval in the same direction as the bent portion of the outer electrode, and two protrusions are formed on the tip surface of the outer electrode at a predetermined interval. A spark plug characterized by forming two protrusions that correspond to the protrusions.
