OXIDE SUPERCONDUCTIVE CONDUCTOR, AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide an oxide superconductive conductor capable of preventing a warping of a base material due to formation of an oriented intermediate layer at a low cost; and to provide its manufacturing method. SOLUTION: This oxide superconductive conductor has: a tape-like base material; the oriented intermediate layer formed on one-side surface of the base material by connecting multiple crystal grains to one another with orientation thereof controlled; and an oxide superconductive layer formed on the oriented intermediate layer. The oxide superconductive conductor is characterized by forming a tensile stress film made of a thin film having tensile stress between the base material and the oriented intermediate layer.
