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 1):
A spark plug comprising:\n a cylindrical metal shell; a cylindrical porcelain insulator which is retained inside the metal shell; a center electrode which is disposed inside the porcelain insulator to have a head protruding outside a front end surface of the porcelain insulator; and a ground electrode which is joined to the metal shell and has a gap-defining portion, the gap-defining portion extending over a side surface of the center electrode and the front end surface of the porcelain insulator.
