<p><P>PROBLEM TO BE SOLVED: To provide an ignition coil for an internal combustion engine configured such that when a primary coil is wound, a pair of winding ends of the primary coil are directly locked to a connector part and damaging of an insulating coating provided to an electric wire constituting the primary coil is effectively suppressed, and to provide a method of manufacturing the same. <P>SOLUTION: The ignition coil for the internal combustion engine includes: the primary coil 21 and a second coil which are arranged in piles on inner and outer peripheries; a center core 23 which is formed by compression-molding soft magnetic material powder and arranged on the inner peripheral side of the primary coil 21 and secondary coil; and a connector part 3 which is made of a thermoplastic resin and electrically connects the primary coil 21 and secondary coil to the outside. The center core 23 is fitted in a fitting hole 34 formed in the connector part 3. The primary coil 21 is wound around an outer periphery of the center corer 23 united with the connector part 3. The pair of winding ends 211 of the primary coil 21 are locked to the connector part 3. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
