Abstract
Provided is an ignition device for an internal combustion engine which prevents a crack from being produced in a cast insulating resin, and a noise-suppressing resistor from being damaged. An ignition device for an internal combustion engine according to the present invention includes a case (), a cast insulating resin (), a high-voltage connection terminal (), and a noise-suppressing resistor (). The case () is composed of a case body () receiving a transformer () and a high-voltage tower () having an opening portion (), and the case body () and the high-voltage tower () communicate with each other through the opening portion (). The cast insulating resin () is injected into the case body () and cured, thus insulating and fixing the transformer (). The high-voltage connection terminal () closes the opening portion () such that the cast insulating resin () that has not been cured is prevented from entering the high-voltage tower (). The noise-suppressing resistor () is arranged in the high-voltage tower (), is electrically connected to the high-voltage connection terminal (), and suppresses noise generated by a discharge of the spark plug ().
