TERMINAL STRUCTURE OF TAPE LIKE SUPERCONDUCTING WIRE MATERIAL AND MANUFACTURING METHOD OF THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a terminal structure of a tape-like superconducting wire material which makes superconducting characteristics less likely to be deteriorated and preferably joins the tape-like superconducting wire material with a metal terminal when the tape-like superconducting wire material and the metal terminal are joined.SOLUTION: A terminal structure of a tape-like superconducting wire material includes: a superconducting tape 20 where a superconducting layer is provided on a base material through an intermediate layer and a protection layer is provided on the superconducting layer; a metal terminal 30; and a connection tape 40 which is disposed between the metal terminal 30 and a terminal 20a of the superconducting tape 20, is joined to the metal terminal 20 by first solder 52, and is joined to the superconducting tape 20 by second solder 54 having a melting point lower than the first solder 52.
