Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an ignition coil for an internal combustion engine using arc welding for an electrically bonded joint portion in place of soldering or resistance-welding. SOLUTION: The ignition coil for internal combustion engine includes a joint portion which is bonded by arc-welding portions to be electrically connected. Since the joint portion is formed by melting the portions to be welded, it can be easily inspected visually, and welding work adapted to a portion in a narrow space can be carried out by a single arc welding apparatus. Thus, investment in equipment can be reduced in mass production. The joint portion in the ignition coil for the internal combustion engine has high resistance and reliability with respect to the vibration or heat cycles of an automobile etc. COPYRIGHT: (C)2009,JPO&INPIT
