Abstract:
A spark plug includes a main ground electrode having a main connecting portion connected to the housing and forming a discharge gap between the main ground electrode and the center electrode, and a sub ground electrode having a sub connecting portion connected to the housing. The direction on which the main connecting portion and a plug center axis are arranged is set to be perpendicular to an air flow direction of an air stream in the combustion chamber. The sub connecting portion is located in a downstream side than the main connecting portion. The tip end position of the sub ground electrode in the plug axial direction is located in farther tip end side than that of the main ground electrode is. The sub ground electrode is configured such that an end point of the discharge spark is movable on the sub ground electrode.

Claim (Index 7):
The spark plug according to  claim 6 , wherein\n the groove portion is configured such that cross-sectional shape parallel to both of a longitudinal direction and the plug axis direction is a curved shape in which the base end side in the plug axial direction is protruded.
