PURPOSE:To retain superconductivity for a long time by providing an oxide film of SiO2 and Al2O3 etc., or a nitride film of Si3N4 etc., or a mixed film or a multilayer film of these elements on the surface of moldings of a linear material, plate material, shape material, or wiring material comprised of a high temperature superconductive material. CONSTITUTION:A protective film with a SiO2 film by plasma CVD, or a protective film with a ITO film by plasma CVD, or a conductive film 2 is formed on the surface of a high temperature superconductive material 1 comprised of a YBaCU system oxide after oxygen plasma is treated. Thus superconductivity can be retained for a long time with loss of superconductivity of materials or increase in contact resistance prevented. |
