Abstract
This ignition coil includes: a bar-shaped resistor electrically connected to a terminal of a coil assembly via a relay; a case for storing these; and a filler filling gaps inside the case. The case includes a body, a cylindrical output portion protruding from the body, and an annular holding portion protruding inward from an inner circumferential surface of the output portion and formed integrally with the output portion. A part of the resistor is inserted into the holding portion, and thus a first internal area located on the body side with respect to the holding portion and shut off from outside is formed in an internal area of the output portion. The filler fills the first internal area.
