PURPOSE:To seek to prevent lowering of an oxygen amount and improve superconductivity by constituting the glass fiber covered with oxide superconductor layer out of a glass fiber, a layer of non-oxidizing substance coated round the glass fiber and a layer of oxide superconductor covering the periphery of this non-oxidizing substance layer. CONSTITUTION:As a non-oxidizing substance constituted of a glass fiber 1, a layer of non-oxidizing substance coated round the glass fiber 1 and a layer 2 of an oxide superconductor covering the periphery of this non-oxidizing substance layer, noble metals such as silver (Ag), gold(Au), platinum(Pt) and palladium(Pd), etc., or alloy made of them as a base can be used. Accordingly, the oxygen in the oxide superconductor layer 2 can be prevented from being robbed by the glass. Hereby, sufficient oxygen amount can be secured in the layer of the oxide superconductor and the deterioration of the superconductivity at the critical temperature or at the critical current can be prevented.
