PROBLEM TO BE SOLVED: To provide a connection structure of an oxide superconducting wire which prevents reduction of superconducting characteristics caused by infiltration of moisture at an end portion.SOLUTION: A connection structure of a pair of oxide superconducting wires comprises an oxide superconducting laminate including a tape-like base material, a middle layer and an oxide superconducting layer, and a stabilizing layer which covers at least the oxide superconducting layer. The connection structure has: the pair of oxide superconducting wires whose end portions are adjacently arranged in a facing manner; an oxide superconducting wire for connection which has a laminate structure equal to the pair of oxide superconducting wires and is arranged bridging between end portions of the pair of oxide superconducting wires so as to stride the end portions; a conductive bonding material which bonds the pair of oxide superconducting wires and the oxide superconducting wire for connection; and a covering member which covers the pair of oxide superconducting wires and the oxide superconducting wire for connection at a portion bonded by the conductive bonding material, and an outer periphery of the pair of oxide superconducting wires at both sides portions in a longitudinal direction of the bonded portion, via a bonding layer. |
