Abstract
The purpose of the present invention is to obtain a low-cost and easy-to-produce ignition coil for an internal combustion engine. A lead wire 13a of an electronic part 13 is connected to a terminal 12a and a terminal 7a of an intermediate conductor 12 by means of caulking or press fitting. Since the end cut face of the lead wire 13a of the electronic part 13 is sharp, a wall material 71 and a cover 81 as crack spread preventing materials are arranged so as to encircle that end cut face. Further, an opening portion 92 is closed by the intermediate conductor 12, and high voltage is output via a spring 11 directly contacted to the intermediate conductor 12. The number of components may thus be reduced, and cracks generating in an insulating resin may be prevented from spreading.
