Abstract

A RE-Ba-Cu-O type oxide superconducting material (RE represents Y, Nd, Sm, Eu, Gd, Dy, Ho, Er, Tm, Yb, Lu or a combination of two or more of them) having a phase structure including a REBa.sub.2 Cu.sub.3 O.sub.y phase and a RE.sub.2 BaCuO.sub.5 phase of 20 .mu.m or less in diameter dispersed in the REBa.sub.2 Cu.sub.3 O.sub.y phase, in which superconducting material RE consists of at least two elements selected from Y, Cl, Nd, Sm, Eu, Gd, Dy, Ho, Er, Tm, Yb and Lu. Said oxide superconducting material can be produced by melt processing.
