Abstract:
1. An ignition coil device of a bent type, comprising: a case having a transformer structure with a primary coil and a secondary coil therein; a high voltage tower including a high voltage terminal that transmits a high voltage developed in the secondary coil to a lower portion of the case; and a plug boot that electrically and mechanically connects the high voltage terminal, the high voltage tower to an ignition plug, includes a boot base close to the high voltage tower and a boot leading end close to the ignition plug in which a center axis of the high voltage tower and a center axis of a boot leading end are tilted, wherein a bend position is set in the vicinity of an intersection point of the center axis of the high voltage tower and the center axis of the boot leading end, and a rigid intermediate member including a connection relay member that electrically connects the high voltage terminal and the ignition plug is provided, and the rigid intermediate member extends from the boot base to the bend position.
