摘要： By grounding a metal first housing, radiation noise generated from the coupling circuit is shielded. Further, by enclosing the first housing in a metal second housing in a manner such that the first housing and the second housing do not come into contact with each other, and grounding the second housing by connecting the second housing to an engine block, radiation noise generated by the capacitive component between the coupling circuit and the first housing is shielded by the second housing. As a result, the influence of this noise on peripheral devices of the high frequency discharge ignition device can be suppressed.

摘要： In a metallic shell, cutting traces are formed on the inner circumferential surface of a trunk portion and the inner circumferential surface of an elongated leg portion. A first portion of a packing is in contact with and disposed between the rear end surface of a ledge portion of the metallic shell and the outer circumferential surface of a step portion of an insulator. A second portion of the packing is in contact with and disposed between the inner circumferential surface of a trunk portion of the metallic shell and the outer circumferential surface of a tubular portion of the insulator. A gap between the inner circumferential surface of the elongated leg portion and the outer circumferential surface of the leg portion is approximately uniform along the entire circumference.
