Abstract
In a first embodiment, an ignition coil includes a disk-shaped primary coil section having a primary coil winding wound thereon and a disk-shaped secondary coil section having a secondary coil winding wound thereon, the primary coil section and secondary coil section facing each other. A core of each winding is aligned with each other to form a coil member. The coil member has a thickness parallel to the thickness direction of the primary and secondary coil sections of from about 10 mm to about 25 mm. The coil member has radial core sections installed on its lower and upper surfaces and is accommodated inside a case member and fixed to the case member by insulation resin injected into the case member. In a second embodiment, a coil winding is wound between upper and lower flange portions of a primary coil winding seat. The axial width of the coil winding is substantially equal to the interval between the pair of flanges.
