ABSTRACT:
An ignition device for an internal combustion engine comprises an ignition coil unit including a core a primary coil wound around said core, a secondary coil electro-magnetically coupled to the primary coil, a case for housing the core, the primary coil and the secondary coil therein, and control circuit for controlling a current flowing the primary coil. In the ignition device, the control circuit is housed in the case so that heat generated by said control circuit is transferred to the case to radiate out the heat.
