PURPOSE:To reduce heat generated in connected portions of superconductors and obtain the connected portions of small size by giving an inclination to the exposed length of superconductive wires, and joining them in order from shorter ones to longer ones. CONSTITUTION:Wire rods 1 of two superconductors 10 arranged in parallel are connected one to one or plural to plural. The wire rods 1 become longer toward the outside from the inside of the two superconductors 10, and are joined in order from short ones to long ones to each other to obtain a crest joined shape. A supersonic junction method is used as the method. Namely, the inclined length of the superconductive wires 1 enables the superconductive wires to be securely joined with excellent operability. Therefore, Joule heat generated in a connected portion 7 can be restrained to be small, and moreover, the length of the connected portion 7 can be set suitably. |
