CONNECTION STRUCTURE OF SUPERCONDUCTIVE WIRE, SUPERCONDUCTIVE WIRE, AND CONNECTION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a superconductive wire which has high connection strength and is adequately conducted; a connection structure thereof; and a connection method thereof.SOLUTION: In a connection structure 100 in which two superconductive wires 10 having a superconductor layer 3 formed on one face side of a substrate 1 through an intermediate layer 2 are connected to each other on mutual connection ends. the superconductor layers of the two superconductive wires are aligned along the same plane, and the substrates of the two superconductive wires are aligned along the same plane. The connection structure 100 includes a first intermediate superconductor layer 32 which is grown and formed in any range between the end surface on the connection end side of one superconductive wire to the end surface of the connection end side of the other superconductive wire. Any one of the positions of the end surfaces on the connection end side of the substrate of the two superconductive wires is out-of-range of the first intermediate superconductor layer in the longitudinal direction of the two superconductive materials.SELECTED DRAWING: Figure 2
