<p><P>PROBLEM TO BE SOLVED: To provide an ignition coil which does not necessarily require a thermal stress relaxing member and is hence capable of reducing its assembling man-hours. <P>SOLUTION: The ignition coil 1 is equipped with a rod-shaped center core unit with a center core 21, a cylindrical internal circumferential side spool 22 arranged on the outer circumferential side of the center core, an internal winding 23 which is wound on the outer surface of the internal circumferential side spool 22 and equipped with a leader 230 that is extracted from the axial end of the internal circumferential side spool 22, and an axial end resin body 40 which is arranged at the one axial end of the internal circumferential side spool 22 to fix the leader 230. The one axial end 210 of the center core unit is held by the axial end resin body 40, and the other axial end is held by the bottom 221 of the internal circumferential side spool 22. <P>COPYRIGHT: (C)2004,JPO&NCIPI</p> |
