Abstract
A method for making superconductive ceramics laminates comprises forming a thick film of a composite oxide comprising bismuth, strontium, calcium, copper and oxygen on a flat plane of a substrate, and orienting and crystallizing the thus formed film by heat treatment to cause the c-axis of composite oxide crystals to be substantially perpendicular to said flat plane of said substrate. An intermediate layer formed of a noble metal, MgO, SrTiO.sub.3, yttria-stabilized zirconia or an oxide of a superconductive ceramics-constituting element may be interposed between the film and the substrate.
