Abstract
An ignition coil includes a center core, a primary coil a secondary coil, a coil housing, a tower housing disposed under the coil housing, and a high tension terminal disposed inside the tower housing. The high tension terminal has an upper flange disposed at a first circumferential gap opposite the inside surface of the tower housing and a middle barrel disposed at a second circumferential gap opposite the inside surface of the coil housing. The first circumferential gap is made smaller than the second circumferential gap. The tower housing or the upper flange has a void-purging passage for purging air from the insulation resinous members when filled in the coil housing.
