摘要
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 capacitor 116 connected to a high-voltage terminal, for preventing passage of high voltage; and an inductor 117 connected to the capacitor 116 and forming, together with the capacitor 116, a band pass filter that allows only a predetermined frequency component to pass. High-frequency current is supplied from outside to the inductor 117. The high-frequency discharge ignition coil apparatus further includes a current level detection device 115 for detecting the level of current flowing in the inductor 117. The current level detection device 115 is placed in one package, together with a primary coil 111, a secondary coil 112, a capacitor 116, and an inductor 117. 展开▼
