Abstract:
1. An ignition device for an internal combustion engine comprising: a transformer that has a primary winding and a secondary winding; a case that is composed of a case body receiving the transformer, and a high-voltage tower having an opening portion, the case body and the high-voltage tower communicating with each other through the opening portion; a cast insulating resin that is injected into the case body and cured and thus insulates and fixes the transformer; a high-voltage connection terminal that is connected to one end of the secondary winding, closes the opening portion such that the cast insulating resin that has not been cured is prevented from entering the high-voltage tower; a noise-suppressing resistor that is disposed in the high-voltage tower, is electrically connected to the high-voltage connection terminal, and suppresses noise generated at a time of a discharge of an spark plug; and a high-voltage output terminal that is provided in an end portion of the noise-suppressing resistor and outputs a high voltage to the spark plug.
