Claims

[Claims for Utility Model Registration] A high voltage is generated on the secondary side of the ignition coil by suddenly cutting off the current flowing to the primary side of the ignition coil built into the power distribution device, and this high voltage is transferred to the rotor electrode of the power distribution device. and an ignition system for an internal combustion engine that supplies an ignition plug to a spark plug through a side electrode provided in a cap of a power distributor corresponding to a rotor electrode, wherein the spark plug is embedded in a cap of the power distributor, and is connected to the secondary side of the ignition coil and the rotor. A high-voltage power supply line that conducts between the electrodes; and a conductor that is placed facing a part of the high-voltage power supply line and separated by a predetermined distance, and that generates a capacitance for absorbing ignition noise between the high-voltage power supply line and the high-voltage power supply line. Ignition noise prevention device for internal combustion engines.
