Abstract
An ignition device includes: a high frequency power source; a first device having inductance; a second device having capacitance; a discharge GAP; and a shield device which covers a connection portion between the first device and the second device, and is connected to the ground. The high frequency power source supplies AC power to the discharge GAP by using a resonance circuit composed of the first device and the second device, and ignites fuel by discharge plasma generated in the discharge GAP. In the ignition device, the first device, the second device, the connection portion, and the shield device are arranged in the same package and are sealed with an insulating substance.
