Abstract: An ignition control apparatus for engines is provided. The ignition control apparatus is designed to control a switch to release energy stored in a capacitor during spark discharge, thereby supplying a primary current to an other end side opposite a one end of a primary winding of an ignition coil connected to a dc power supply. This provides the ignition control apparatus which is capable of minimizing an increase in size or manufacturing cost and stabilizing the state of combustion of an air-fuel mixture.
