Abstract
An ignition coil for an internal combustion engine is provided which is equipped with a high-voltage connector terminal and a high-voltage output terminal. The high-voltage connector terminal is connected to a secondary coil. The high-voltage output terminal is to be joined to a spark plug. The high-voltage connector terminal has a tip portion with a rounded surface which elastically establishes an electrical contact with the surface of the high-voltage output terminal. The rounded surface serves to minimize the wear of the high-voltage connector terminal and the high-voltage output terminal which arises from rubbing therebetween during assembling or operation of the ignition coil, thus avoiding the adhesion of foreign objects to the contact surfaces and ensuring the stability of electric communication between the high-voltage connector terminal and the high-voltage output terminal.
