Abstract
Provided is a compact ignition coil apparatus that can realize reliable insulation breakdown and spark discharge with high discharge current. A high-frequency discharge ignition coil apparatus includes: a capacitorconnected to a high-voltage terminal, for preventing passage of high voltage; and an inductorconnected to the capacitorand forming, together with the capacitor, a band pass filter that allows only a predetermined frequency component to pass. High-frequency current is supplied from outside to the inductor. The high-frequency discharge ignition coil apparatus further includes a current level detection devicefor detecting the level of current flowing in the inductor. The current level detection deviceis placed in one package, together with a primary coil, a secondary coil, a capacitor, and an inductor
