PURPOSE:To make it possible to manufacture a compound membranous superconductor of a good property easily by applying oxygen ions on a specific complex compound membrane attached to the surface of a base body in order to oxidize the metallic main component in the membrane. CONSTITUTION:For the formation of a membranous superconductor, first a complex compound membrane of oxide including A element, B element, and Cu at the mol ratio of elements, 0.5 <= (A+B)/Cu <= 2.5 is attached on a base body in a physical gaseous phase growing method. In this case, A is at least one of Sc, Y, and lanthan family elements, B is at least one of IIa group elements such as Ba, Sr, Ca, Be, and Mg. Then, the complex compound membrane is treated further by oxygen ions which are grown by the discharge of a gas including oxygen. In this case, the base body is heated at a temperature between 400 deg.C and 800 deg.C.
