OXIDE SUPERCONDUCTIVE WIRE MATERIAL, CONNECTION STRUCTURE OF OXIDE SUPERCONDUCTIVE WIRE MATERIALS, AND METHOD FOR MANUFACTURING AN OXIDE SUPERCONDUCTIVE WIRE MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide an oxide superconductive wire material capable of preventing the deterioration of the superconductive characteristic due to invasions of water into terminal portions thereof; and a connection structure of the oxide superconductive wire materials.SOLUTION: The provided oxide superconductive wire material is an oxide superconductive wire material comprising: an oxide superconductive laminate possessing a tape-shaped substrate, an intermediate layer, and an oxide superconductive layer; and a stabilization layer covering at least the oxide superconductive layer side of the former. The longitudinal terminal portion of the oxide superconductive laminate is covered with a distal end coating layer including Ag. Moreover, the provided connection structure of oxide superconductive wire materials is a connection structure of oxide superconductive wire materials obtained by connecting one of the oxide superconductive wire materials to the other and possessing, in addition to a pair of oxide superconductive wire materials, oxide superconductive wire materials for connection each having a structure identical to that of the former in a state where the oxide superconductive wire materials for connection are joined while straddling and bridging the first and second oxide superconductive wire materials arranged while mutually adjacent members of the respective longitudinal terminal portions thereof oppose one another.
