Abstract
An 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 electrically connected between the secondary coil and one of the electrodes of the ignition plug; and a case made of an insulating material having a noise suppression element containing unit. The device is characterized by including ribs disposed in the noise suppression element containing unit and 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 containing unit and makes contact with the ribs and the noise suppression element.
