Abstract
An ignition coil includes a primary coil, a secondary coil, a center core, an outer core, an igniter, a coil case and an electrically-insulative fixation resin. On an interior surface of the coil case on a bottom part side in a mounting direction, there is formed a case-side rib to protrude from the interior surface of the coil case to a high-voltage side in an axial direction. The case-side rib has a taper shape such that the protruding amount of the case-side rib to the high-voltage side in the axial direction increases in the mounting direction toward the bottom part side. The case-side rib is arranged to abut a corner portion of the igniter on the bottom part side in the mounting direction and on a low-voltage side in the axial direction and thereby press the igniter against the outer core.
