PURPOSE:To make it possible to form a superconduction electronic device applying a ceramic superconductive material, by arranging, on a substrate, YSZ, yttria or zirconia, which are in the form of a thin film and closely in contact with a material generating an oxide superconductive ceramic. CONSTITUTION:A substrate 1 has a surface with a desired shape of YSZ (yttrium stabilized zircon), yttria or zirconia. By a sputtering method or a printing method, a thin film type cermic material 2 is formed on the surface of the substrate 1 so as to be closely in contact with the surface. The ceramic material 2 formed on the surface of the substrate 1 is selectively irradiated by laser light and scanned to transform the irradiated parts only into an oxide superconductive material 4. The residual region 5 in the periphery is turned substantially into an insulating region. In this manner, the ceramic superconductive material 4 is arranged so as to be in contact with YSZ, zirconia or yttria. Thereby, the constitution substantially in the form of a coil, a disc, a film, a line or a belt is enabled.
