ABSTRACT:
An ignition device includes a capacitor 119, a semiconductor switch element 104 and an ignition control circuit 101, by which the cut-off of current supply to the ignition coil 105 is made gradual by supplying charge of the capacitor to the semiconductor switching element when the engine is stopped or the stop switch 117 is operated, the problems caused by undesired abrupt cut-off of the ignition current are eliminated.
