プラグ。In a spark plug in which a center electrode is insulated by an insulator and a distal end of the center electrode is opposed to a ground electrode to form a discharge gap, a heater is buried inside the combustion part exposed insulator that insulates the center electrode. An ignition plug characterized in that the heater is energized to burn and remove solid matter such as soot adhering to the surface of the exposed combustion part insulator.
