Abstract

An ignition coil has a primary coil and a secondary coil, a coil terminal, a connector terminal and a connector part. The connector part has a coil-side lead wire and a connector-side lead wire. The coil terminal has a coil-side fitting groove part into which the coil-side lead wire is fitted. An internal edge surface of the coil-side fitting groove part is formed internally to have a protruded curved surface. The connector terminal has a connector-side fitting groove part into which the connector-side lead wire is fitted. An internal edge surface of the connector-side fitting groove part is formed internally to have a protruded curved surface. The coil-side lead wire is inserted into the coil-side fitting groove part in a direction perpendicular to a longitudinal direction thereof. The connector-side lead wire is fitted into the connector-side fitting groove part in a direction perpendicular to a longitudinal direction thereof.
