PURPOSE:To prevent carbon grains or glass grains from being adhered to the bonding area on the top of a lead post and to prevent the position of the lead with respect to an eyelet from being out of order by denting inwardly a bonding area, which connects a wire on the top of a lead post at the upper end of the lead, to the inner side of the lead. CONSTITUTION:A bonding area 14, which connects a wire in the center of the top of a lead post 12 on the upper end of a lead 10, is dented into the inner side of the lead post 12 in recessed shape or circular shape. When the lead 10, which is adapted to stand on its top, is incorporated into a jig 20 made of carbon, a bonding area 14 fits and lifts the lead post 12 to the upper part of the bottom, preventing the top of the lead from coming contact with the bottom of a recessed part 22 in the jig. |
