Abstract (en)
To provide an ignition device that can improve an air-fuel ratio in an internal combustion engine without a device size enlargement or a high cost performance. The ignition device comprises a center conductor configured to propagate an electromagnetic wave on a surface thereof, a ground conductor for surrounding the center conductor, a second center conductor in a cylindrical manner formed between the center conductor and the ground conductor, insulated from the ground conductor, connected to the center conductor at a rear end side, while spaced away from the center conductor at a front end side, an electromagnetic wave resonation structure formed by the center conductor and the second center conductor, and a projecting discharge electrode part formed at a side surface of a distal end part of the center conductor. A potential at the discharge electrode part is boosted by use of the electromagnetic wave resonation structure, and a discharge is caused between the discharge electrode part and the ground conductor.
