Abstract
An ignition coil for an internal combustion engine is provided which includes a case, a connector, a resinous member, and a retainer. The case is equipped with an opening portion and has component parts mounted therein. The connector is electrically connected to an external device. The resinous member is disposed in the case. The retainer firmly hold an external connecting member joined to the connector. The retainer is mechanically discrete from the case and secured to an attachment wall of the case. The attachment wall is defined by at least one of a wall of the case which constitutes the opening portion and a wall secured to the opening portion. The retainer has a portion embedded in the resinous member. This structure minimizes fretting wear between terminals of the connector and the external connecting member such as a wire harness.
