Claim:
1. A superconducting element comprising: a metallic substrate; a superconductor layer; a metallic protective layer; and an insulating layer disposed between said substrate and said superconductor layer, wherein, in cross-section of the superconducting element, said insulating layer extends at both ends thereof past an area of said substrate covered by said superconductor layer to galvanically separate said superconductor layer and said metallic protective layer from said substrate, said insulating layer thereby having a thickness which is selected in such a fashion that the superconducting element has a transverse breakdown voltage between said metallic substrate and both said superconductor layer as well as said metallic protective layer of at least 25 V, wherein said metallic protective layer contacts said insulating layer.
