Ignition is performed in such a way that a bias voltage is applied to a first electrode of an ignition plug and a current detection device detects a current that flows in the first electrode, that based on the value of the detected current, a smolder level detection device detects the level of a smolder produced in the ignition plug, and that a control device controls, based on the detected smolder level, at least one of the timing of ignition, the number of ignition events per power stroke of an internal combustion engine, and the amount of energy accumulated in an ignition coil device.
