A power supply output supply blocking circuit is provided which compares the voltage between the gate and cathode of the thyristor with a set voltage and blocks the output of the power supply circuit from being supplied to the capacitor when the voltage between the gate and cathode exceeds the set voltage. A capacitor discharge type ignition device for an internal combustion engine, characterized by: (2) The power output supply blocking circuit compares the gate-cathode voltage of the thyristor with the set voltage and changes the potential of the output terminal depending on the magnitude relationship between the gate-cathode voltage and the set voltage. and an output terminal of the comparison circuit is connected to the converter so as to stop the operation of the converter when the voltage between the gate and cathode of the thyristor exceeds the set voltage. The ignition device for a capacitor discharge type internal combustion engine according to claim 1.
