<p>The present invention provides a high-temperature oxide superconductor which comprises an oxide expressed as (Bi1-x Ax) - By - Cz -Cu oxide (where A is Sb and/or As; B and C are elements different from each other, each being one or more elements selected from Be, Mg, Ca, Sr and Ba; and 0 </= x < 1, 0 < y </= 5 and 0 < z </= 5). According to the present invention, it is possible to manufacture a high-temperature oxide superconductor having a transition temperature of over 100 K and not containing a rare-earth element at all, and to manufacture a superconductor excellent in reliability and stability more easily than conventional superconductors such as Y-Ba type superconductors.</p> |
