<p>PROBLEM TO BE SOLVED: To provide an ignition coil that has high reliability by suppressing cracking and water permeation by covering the position of a molding injector pin of a core cover with a filling resin and other members.SOLUTION: An ignition coil includes a side face iron core molding 10 which has a part of a side face iron core 100 covered with a core cover 101 formed by molding, and the part is exposed from an insulation resin 40. An injector pin for pushing the side face iron core molding 10 out of a metal mold for molding after the core cover 101 is molded is arranged in a position where an injector pin trace 102 formed when abutted on the side face iron core molding 10 and a weld line WL formed on the core cover 101 are not at the same position.</p> |
