PURPOSE: To provide electric connecting pieces which are welded with laser beams easily and manufactured at low cost, by processing same plate material as material of a glass-sealing-treated electric conductive lead group and covering with an insulating tape its region except both ends' connecting part. CONSTITUTION: An electric connecting piece 3 is formed by stamping out using a press from a metal plate whose material has the same or the approximate melting point to that of an glass-sealing-treated electric conductive lead group in specified intervals. An insulation region 5 in which both sides of the entire electric connecting piece 3 group is covered with an insulating tape is formed in partial region between its one end 7 and another end 8. And a holding section 24 which keeps intervals between electric connecting pieces 3 in the electric connecting piece 3 group is cut off, and an actuator 11 of a terminal connecting electric connector is attached to the another end 8. The one end 7 is connected to the glass-sealing-treated electric conductive lead group with laser beam welding. Heat is radiated effectively by arranging a heat radiating space 6 in intermediate range of the insulated region 5. |
