Abstract
A stick-shaped ignition coil includes a primary and secondary coils, a plurality of annular protrusions, a thin film sheet, a sub-assembly and a case. The annular protrusions are integrally formed on the outer circumferential periphery of the upper end portion of the primary coil arranged on the radially outer side. The thin film sheet covers the primary coil and the outer circumferential periphery of the plurality of annular protrusions. The sub-assembly is press-inserted to the outer circumferential periphery of the plurality of annular protrusions via the thin film sheet. The sub-assembly, which is electrically insulative, supports a lead portion of the primary winding. The case is press-inserted to the outer circumferential periphery of the cylindrical member.
