Abstract:
A spark plug is provided which includes a cylindrical metal shell, a cylindrical porcelain insulator retained in the metal shell, a center electrode, and a ground electrode. The center electrode is disposed in the insulator with a head protruding outside a front end surface of the insulator. The ground electrode is joined to the metal shell and includes a gap-defining portion which faces a side surface of a side surface of the center electrode to define a spark gap and also faces the front end surface of the porcelain insulator to define a semi-surface discharge gap for burning off, for example, carbon deposits on the front end surface of the insulator.

Claim (Index 4):
A spark plug as set forth in  claim 1 , wherein the gap-defining portion defines a first gap that is a minimum gap between the gap-defining portion and the side surface of the center electrode, the first gap being selected to be more than or equal to 0.4 mm and less than or equal to 0.8 mm, and wherein the gap-defining portion defines a second gap that is a minimum gap between the gap-defining portion and the front end surface of the porcelain insulator, the second gap being selected to be more than or equal to 0.2 mm and less than or equal to the first gap.
