The ignition device is comprised of a center electrode, an insulator having a tubular shape for covering the center electrode, and a ground electrode having an open portion communicating with an open portion of the insulator, the ground electrode covers the insulator The center electrode, the insulator and the ground electrode define a discharge space of the ignition device. The discharge space is provided with high voltage from a discharge power source and high current from a plasma energy supply power source to form plasma having high temperature and high pressure in the discharge space.
