Internal combustion engine ignition coil device

Abstract

An internal combustion engine ignition coil device according to the present invention is provided with a primary coil to which a primary current is applied; a secondary coil that is magnetically coupled with the primary coil and generates an ignition voltage when the primary current is cut off, so as to produce a spark discharge between a pair of electrodes of an ignition plug; a noise suppression element that is electrically connected between the secondary coil and one of the pair of electrodes of the ignition plug; and a case that is made of an insulating material and has a noise suppression element containing unit for containing the noise suppression element. The internal combustion engine ignition coil device is characterized by including ribs that are disposed in the noise suppression element containing unit and are arranged in such a way as to face the outer circumferential surface of the noise suppression element and a resin insulating material that is filled into the noise suppression element containing unit and makes contact with the ribs and the noise suppression element.
