<p>A holder 6 having a funnel-shaped portion is provided above an eyelet 5, and a conductive metal piece 11 is supplied to the vicinity of a portion at which plasma arc welding is performed in the funnel-shaped portion. The conductive metal piece 11 is fused together by plasma arc welding so that the hole 9 of the eyelet is closed completely. Thus, the lead wire 8 can be connected firmly. Therefore, even if the hole diameter of the eyelet is excessively large relative to the diameter of the lead wire, complete closure and sufficient fusion connection can be achieved. <IMAGE></p> |
