摘要： An ignition apparatus which facilitates improvement in energy efficiency as well as materializing an excellent ignitability through effectively utilizing energy used for inductive discharge as a blowout power. The ignition apparatus is used for an ignition plug that includes a center electrode, a ground electrode and a cavity surrounding at least a portion of a clearance formed between the two electrodes to thereby form a discharge space. The ignition apparatus includes a voltage application portion which applies voltage to the clearance and a power supply portion which supplies electric power to the clearance. In addition, a capacitance portion for storing a capacitance is provided, in parallel with the ignition plug, in a voltage application path of the voltage application portion.
