Abstract:
A spark plug for an internal combustion engine is provided which has a center electrode and a ground electrode. The ground electrode includes an upright portion extending in a lengthwise direction of the spark plug and an extension bent from the upright portion in a radial direction of the spark plug. The extension has a slant surface which is shaped to be inclined away from the center electrode downstream in a flow of air-fuel mixture within a combustion chamber when the spark plug is mounted in the engine. This results in an increase in in distance by which a starting point on the ground electrode where a spark is created is moved on the slant surface, thereby increasing a length of time the spark is moved downstream and then blown out to increase the probability of successful ignition of the air-fuel mixture.

Claim (Index 2):
A spark plug as set forth in  claim 1 , wherein the extension also has an inner extension surface and an outer extension surface which is opposed to the inner extension surface and located farther away from the center electrode, the outer extension surface including an outer slant portion which is inclined away from the center electrode from the Y 1  side to the Y 2  side.
