Abstract
To provide an ignition device for an internal combustion engine which for example prevents a crack from being made in a cast insulating resin or a transformer output voltage control element from being damaged. The ignition device for an internal combustion engine of the present invention includes: a transformer (); a case () that is composed of a case body () receiving the transformer (), and a high-tension tower () having an 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 closes the opening portion () such that the cast insulating resin () that has not been cured is prevented from entering the high-tension tower (); a noise-suppressing resister () that is received in the high-tension tower (), is electrically connected to the high-voltage connection terminal (), and controls a voltage generated in the second winding in activating the transformer (); and a spring () that electrically connects the noise-suppressing resister () and a spark plug to each other, and urges the noise-suppressing resister () toward the high-voltage connection terminal ().
