Abstract
Impurities are reduced in an oxide superconducting layer and in an interface between the oxide superconducting layer and an intermediate layer. A superconducting wire rodhas a structure including a substrate (), an intermediate layer () formed on the substrate (), a reaction suppressing layer () formed on the intermediate layer () and mainly containing polycrystalline SrLaFeOor CaLaFeO, in which the δ1 and the δ2 each represent an amount of non-stoichiometric oxygen, and an oxide superconducting layer () formed on the reaction suppressing layer () and mainly containing an oxide superconductor.
