摘要： PURPOSE:To maintain and show always a state of a relatively high critical current density Jc by covering aluminum dispersion strengthened copper layer on an external surface of a Ag matrix or a Ag strengthened matrix. CONSTITUTION:A Ag matrix 1 or a Ag strengthened matrix, a oxide superconductor 2 which are provided as multiple cores separated between each other in the matrix 1 to extend along the axial direction, and an aluminum dispersion strengthened copper layer 3 provided with oxygen gas provision holes for covering outer surface of the line-shaped matrix 1, are composed. By composite effect due to softening of the Ag matrix by heat treatment and the aluminum dispersion strengthened copper layer 3 maintaining relatively high strength, external weighting is dispersed effectively and strength is up as a result. Accordingly, influence of an electromagnetic stress (hoop force) of a magnet is largely reduced and degradation of a critical current density Jc is also suppressed.
