Connecting structure of oxide superconducting wire and method of manufacturing the same

A method of manufacturing a connecting structure of an oxide superconducting wire, the method comprising:

• preparing a pair of oxide superconducting wires each having a first oxide superconducting layer and a first stabilized layer, which are sequentially deposited on a first tape-shaped base material, a first surface-connecting superconducting wire having a second oxide superconducting layer and a second stabilized layer, which are sequentially deposited on a second tape-shaped base material, and a second surface transit connector;
• disposing the pair of oxide superconducting wires such that tip surfaces thereof face to each other;
• joining the first surface-connecting superconducting wire to the pair of oxide superconducting wires such that the second stabilized layer faces to the first stabilized layer of the pair of oxide superconducting wires;
• joining the second surface transit connector to the pair of oxide superconducting wires to face to the first base material of the pair of oxide superconducting wires;
• and
• setting tensile strength of joining sections between the second surface transit connector and the pair of oxide superconducting wires to be larger than tensile strength of joining sections between the first surface-connecting superconducting wire and the pair of oxide superconducting wires, when the first surface-connecting superconducting wire and the second surface transit connector are joined to the pair of oxide superconducting wires.
