Summary:Impurities are reduced in an oxide superconducting layer and in an interface between the oxide superconducting layer and an intermediate layer. A superconducting wire rod 1 has a structure including a substrate (10), an intermediate layer (20) formed on the substrate (10), a reaction suppressing layer (28) formed on the intermediate layer (20) and mainly containing polycrystalline SrLaFeO4+δ1 or CaLaFeO4+δ2, in which the δ1 and the δ2 each represent an amount of non-stoichiometric oxygen, and an oxide superconducting layer (30) formed on the reaction suppressing layer (28) and mainly containing an oxide superconductor.
