ABSTRACT:
Superconducting composite comprising a matrix made of superconducting sintered mass composed of perovskite type or quasi-perovskite type oxide and metal phase dispersed in the superconducting mass with a proportion of from 10 to 70 volume % with respect to said composite. The metal phase may consist of at least one of Cu, Ag, Au, Pt, Ni and Zn or their alloys. The superconducting sintered mass may be Ba-Y-Cu-O type compound oxide.
