PROBLEM TO BE SOLVED: To improve the critical current characteristics while suppressing increase in the types of material.SOLUTION: The oxide superconducting thin film includes a substrate, a superconductive layer including a plurality of RE-based superconductor units formed on the substrate and composed to include a rare earth element, a CuO chain and a CuOplane, a CuO chain existing among the RE-based superconductor units around the interface of the superconductive layer and a layer adjoining the substrate side of the superconductive layer, out of a plurality of CuO chains, and is 1.2-2 times longer in the lamination direction than the length of a CuO chain determined by the lattice constant of the RE-based superconductor unit, and an edge dislocation adjoining the long CuO chain in the lamination direction. |
