ABSTRACT:
An ignition coil has a connector electrically connected to an external circuit, an igniter for accommodating a switching element adapted to cause a current supplied from the connector to be intermittent, a primary coil portion for generating a predetermined voltage by the intermittent current, a secondary coil portion for stepping up the generated voltage and applying the resulting voltage to an ignition plug, and a resin insulating material which hardens in between the primary coil portion and the secondary coil portion to ensure insulation between the primary coil portion and the secondary coil portion. An outer shell of the igniter is formed of the resin insulating material.
