PURPOSE:To make such a long and stabilizing material-cum-superconductive compound thin film securable by thermally oxidizing a tapelike or pipelike and stringlike Cu substrate, forming a CuO oxide layer there, and then elements L and M or the oxide are deposited on this layer by evaporation, and whereby manufacturing this thin film finally upon heat treatment. CONSTITUTION:First of all, a long tapelike or pipelike, stringlike cu substrate serving as a stabilizing material is thermally oxidized, forming a CuO oxide layer on the surface. Afterward, elements L (=Y, Sc) and M (=Ba, Sr, Ca) or the oxide are deposited by a continuous sputtering device and a vacuum evaporation device and subjected to that treatment. With this process, a long L-M-Cu-O superconductive compound thin film is manufacturable, and it contains the Cu stabilizing material, so that even in case of utilizing it for a superconducting magnet and power line and at the time of normal conductive operation at large current energization, there is no burning at all.
