Abstract
Disclosed herein is a method which enables permanent current junction of a tape-type oxide superconducting wire and suppresses reduction of its critical current. An end portion of a tape-type wire (10) to be joined is removed to expose oxide superconductor filaments. Another tape-type wire (10') to be joined with the wire (10) is processed in a similar manner. The tape-type wires (10, 10') are so superposed that the surfaces exposing the filaments face with each other, and the superposed portions are pressed in a direction perpendicular to principal surfaces of the tapes and heat treated at a temperature of 800.degree. to 900.degree. C., to be completely joined with each other.
