Abstract
A method for producing an oxide superconducting composite wire is disclosed, which comprises the steps of: (a) molding a powdered oxide superconductor material to form a wire; (b) heat treating the wire in an oxygen atmosphere thereby forming the wire into an oxide superconducting member; (c) forming a non-oxidizing metal intermediate layer on a surface of the oxide superconducting member; (d) bundling a plurality of the oxide superconducting members containing the intermediate layer; (e) inserting the bundled oxide superconducting members into an oxidizing metal support tube; and (f) drawing the product of step (e) to reduce its diameter and heat-treating it.
