To reduce effects on mechanical action and reduce shortening of life due to an unavoidable wear by improving a device for igniting an air-fuel mixture by using a high-frequency electric energy source in an internal combustion engine.
This device for igniting the air-fuel mixture by using the high-frequency electric energy source in the internal combustion engine coaxially comprises a wave body structure as a resonator. A high-frequency electric energy can be supplied into the wave body structure, and the wave body structure is projected, at one end, into each combustion chamber of the cylinder of the internal combustion engine. One end of the coaxial wave body structure is formed so that plasma free in the air-fuel mixture can be generated from an ignition pin 12 projected from a field structure rushed into the combustion chamber at a generated voltage potential or a wave body structure. The ignition pin 12 of the device comprises an inner hole 13 at least partially extending through the axial length thereof.
