There is provided an ignition system which is capable of surely operating by electric energy stored in a capacitor for ignition while separating an igniter from electric circuits for communication and ignition without producing improper operation through static electricity and noise and is compact and excellent in the productivity. An ignition system comprises an igniter, which includes a cup body having an opening at one end, a closure plug for sealing the opening of the cup body, an ignition powder filled in the inside of the cup body and an SCB chip mounted on the closure plug and electrically connected to the electrode pins for causing the ignition powder to ignite upon energization, and a connector for connecting the igniter to an ECU, wherein a circuit for ASIC is arranged in the connector to cause ignition by discharge from a capacitor for ignition incorporated in the circuit for ASIC, and a capacitor for electrostatic protection is electrically connected in parallel to the SCB chip within the igniter.
