Abstract

PROBLEM TO BE SOLVED: To provide a favorable electrical bond without requiring large power and to improve the mechanical strength of a junction portion. SOLUTION: An iron reinforcing piece 4 is engaged to an outer circumference of a connector 3 comprising copper and lead wires 1 and 2 comprising copper, and it is pressurized and a current is passed. The mechanical strength is reinforced and durability is enhanced after the junction by rigidity of the reinforcing piece 4. Since the electric resistivity of the reinforcing piece 4 is large, large Joule heat can be provided even by small power. Since the melting point of the reinforcing piece 4 is high, the mechanical strength can be maintained even after thermal press welding.
