Claim:
1. An ignition control device for an internal combustion engine comprising: an ignition coil supplying a discharge voltage to an ignition device of an ignition combustion engine; a voltage-controlled type semiconductor element connected to a primary side of the ignition coil: and an ignition control section capable of repeating multiple times, in an ignition period, of operations of turning ON and turning OFF of the voltage-controlled type semiconductor element by giving a gate signal to a gate of the voltage-controlled type semiconductor element; wherein the ignition control section includes an active element that discharges gate charges accumulated on the gate of the voltage-controlled type semiconductor element to the ground upon turning OFF operation of the voltage-controlled type semiconductor element, and that is connected between the gate and a resistor at a side of the gate inserted in a gate wiring connected to the gate of the voltage-controlled type semiconductor element.
