ABSTRACT:
A plasma jet ignition plug capable of inhibiting occurrence of channeling while reducing removal of energy of plasma through a ground electrode at the time of emission of plasma. A ground electrode of a plasma jet ignition plug projects inward from a front end face of a metallic shell toward an opening end of a cavity which is open at a front end face of an insulator. A projecting distal end which forms a spark discharge gap between the same and a center electrode within a cavity is located inward, with respect to a diametral direction P orthogonal to an axis O, of a position which is located 0.5 mm radially outward from the opening end of the cavity.
