PURPOSE:To realize an oxide superconducting wire by which the characteristic degradation by stress or strain can be completely prevented and a strain resistant characteristic, for example when being formed as a coil can be improved and which functions as a highly reliable coil as well as to manufacture such an oxide superconducting wire. CONSTITUTION:In an oxide superconducting wire provided with an oxide superconductor 3' and a sheath metal type outer periphery covering body which functions as stabilization or the like to integrally cover an outer peripheral surface of this oxide superconductor 3', the metal type outer periphery covering body is composed of at least two layers. The inner most layer 1 is formed of at least one kind of metal selected from Ag, Au, Pd and Pt or a sheath alloy type which contains at least one kind selected from Mg, Al, Si, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Nb, Cd, In and Sn in a range of not exceeding 5 mass% and is selected from Ag, Au, Pd and Pt. The outermost layer 2 is formed of an alloy type (herein, the concentration of an added component is higher in the outermost layer) which contains at least a single kind selected from Mg, Al, Si, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Nb, Cd, In and Sn in a range of 0.01 to 25 mass % and is selected from Ag, Au, Pd and Pt, stainless steel or Ti type alloy. |
