Abstract
An ignition control device comprises: a first switching element having a power source side terminal connected to an other end side of a primary coil and a first ground side terminal connected to a ground side; a second switching element having a second ground side terminal connected to the other end side of the primary coil; a third switching element having a third power source side terminal connected to the second power source side terminal in the second switching element, and a third ground side terminal connected to the ground side; and an energy storage coil. The energy storage coil is an inductor interposed in an electric power line connecting a non-ground side output terminal in a DC power source and the third power source side terminal in the third switching element, and stores energy from the turning on of the third switching element.
