Object: The present invention is intended to supply an internal combustion engine-use igniter that is compact, excellent in mountability, and can contribute to the simplification and automation of assembly and to cost reduction. Implementing means: An insulated gate bipolar transistor (IGBT) is used as the ignition coil switching device for the internal combustion engine. The IGBT and a current limiting circuit intended to protect it from an overcurrent are formed on single semiconductor chip 3, and this semiconductor chip 3 and radio noise reduction capacitor 5 are contained in single packaging unit 4 having external input and output terminals 41 to 44. Packaging unit 4 is transfer-molded using a material such as epoxy resin.
