An ignition control device is described for an internal combustion engine, comprising: (a) first means for producing a signal synchronized with an ignition timing interval of the engine; (b) second means responsive to the synchronized signal produced by the first means for producing a signal indicative of the ignition timing interval and a signal indicative of a time point at which an interval between successive ignition periods is divided into two sections with a predetermined ratio; (c) third means responsible to the ignition timing interval signal and the time point signal from the second means for producing a first signal within a period from a beginning of the ignition timing interval to the time point, and a second signal within a period from the time point to a beginning of a subsequent ignition timing interval; (d) fourth means responsive to either of the first or second signals from the third means for establishing a start time of current supply to an ignition coil means, in dependence upon the establishment of a preceding current supply start time, to provide a current supply signal for the ignition coil means; and (e) switching means responsive to the current supply signal from the fourth means for on-off controlling a current to the ignition coil means.
