Abstract

See full text

An ignition device includes a coil unit and an igniter. The coil unit includes a primary coil and a secondary coil. The primary coil includes a main primary coil and an auxiliary primary coil formed by winding a single primary conductor on a primary bobbin. The secondary coil is formed by winding a secondary conductor on a secondary bobbin. A DC voltage is applied to an intermediate section of the primary conductor between the main primary coil and the auxiliary primary coil. The igniter controls current flowing into the main primary coil or the auxiliary primary coil. The primary bobbin includes a bobbin body and a hooking part protruding from the bobbin body. The main primary coil and the auxiliary primary coil are wound on an outer peripheral surface of the bobbin body to the same direction. A part of the intermediate section is hooked on the hooking part.
