摘要： PROBLEM TO BE SOLVED: To provide an oxide superconductor wire material having a low cost and a high critical current density. SOLUTION: An oxide superconductor wire material comprises a metal base plate, an intermediate layer deposited on the metal base plate by an ion beam assist deposition (IBAD) method, a capping layer consisting of CeO 2 evaporated on the intermediate layer by PLD (Programmable Logic Device) method, and an oxide superconductor wire material consisting of an oxide superconductor film coated on the capping layer. Wherein, a thickness of the intermediate layer is not more than 2000 nm and a thickness of the capping layer is not less than 50 nm. As the above, thickening the capping layer as well as thinning the intermediate layer produced by the IBAD method shortens a deposition time required by the IBAD method, thereby improving the orientation of an obtained superconducting film.
