<p><P>PROBLEM TO BE SOLVED: To solve a problem in which the winding of a secondary coil is broken up to lower the productivity of an ignition coil when forming the spool-less secondary coil with the fusion of self-fusing wire. <P>SOLUTION: A sheet 17 is mounted on the inner peripheral face of the secondary coil 16 on which the self-fusing wire 160 is wound. When fusing the self-fusing wire 160, the secondary coil 16 and the sheet 17 are molded in one unit. This secures the shaping accuracy of the secondary coil 16 to improve the productivity. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
