Abstract
A tape based on a superconducting oxide containing Cu-O, the tape being characterized by the fact that it comprises a substrate of flexible metal or composite material having a rectangular cross-section and provided on at least one of its faces with a cavity-free film of perovskite type superconducting oxide having congruent or quasi-congruent melting or peritectic decomposition close to a eutectic point, the thickness of said film lying in the range 1 .mu.m to 100 .mu.m, the orientation of the C axis of the superconducting crystals being perpendicular to said face of said substrate.
