Abstract:
In a spark plug, a discharge gap is formed between a ground electrode and a central electrode. The ground electrode has a rod-shaped part and an opposing part. The opposing part faces the central electrode, and has a flat surface part and a slope surface part. The slope surface part is formed on a part of the opposing part in an extending direction of the ground electrode, and formed on the opposing part and gradually separated from the central electrode along a width direction of the opposing part. The spark plug has a ratio V/W within a range of 0.5<V/W<2.0. V indicates a length of the opposing part measured in a gap formation direction in which the central electrode, the discharge gap and the opposing part are arranged in order. W indicates a length of the opposing part in the ground electrode width direction.

Claim (Index 1):
A spark plug comprising:\n a spark plug housing having a cylindrical shape; an insulator having a cylindrical shape and being arranged in and supported by an inside of the spark plug housing; a central electrode supported in an inside of the insulator, and a front end part of the central electrode projecting; a ground electrode being arranged to form a discharge gap between the central electrode and the ground electrode, the ground electrode comprising a rod-shaped part and an opposing part, the rod-shaped part extending from a front end part of the spark plug housing toward a front end part of the spark plug, the opposing part having a curved shape which being curved from the rod-shaped part inwardly in a radius direction of the spark plug, and the opposing part facing the central electrode, the opposing part comprising a flat surface part and a slope surface part, the flat surface part having a flat-shaped surface which faces the central electrode side, the slope surface part being formed, on a part of the opposing part in an extending direction of the ground electrode, to be gradually separated from the central electrode along a width direction of the opposing part, wherein the spark plug has a ratio V/W within a range of 0.5<V/W<2.0, where V indicates a length of the opposing part measured in a gap formation direction in which the central electrode, the discharge gap and the opposing part are arranged in order, and W indicates a length of the opposing part in the ground electrode width direction.
