摘要：
Superconducting oxide material containing compound represented by the formula:(Tl.sub.(1-p-q) Bi.sub.p Pb.sub.q).sub.y .gamma..sub.z (.alpha..sub.(1-r) .beta..sub.r).sub.s Cu.sub.v O.sub.win which each of ".alpha." and ".gamma." is an element selected in IIa group of the periodic table, ".beta." is an element selected from a group comprising Na, K, Rb and Cs, "y", "z", "v", "w", "p", "q", "r" and "s" are numbers each satisfying respective range of 0.5.ltoreq.y.ltoreq.3.0, 0.5.ltoreq.z.ltoreq.6.0, 1.0.ltoreq.v, 5.0.ltoreq.w, 0.ltoreq.p.ltoreq.1.0, 0.ltoreq.q.ltoreq.1.0, 0.ltoreq.r.ltoreq.1.0 and 0.5.ltoreq.s.ltoreq.3.0.
