Abstract
A large-area superconductor magnetic shield comprising a plurality of small superconductor unit layers stuck onto the surface of a large-area substrate, wherein the external peripheral sections of the adjacent unit layers are overlapped mutually or the end sections of the adjacent unit layers are abutted mutually such that the adjacent unit layers do not make contact with one another. Compared with conventional magnetic shields, the magnetic shielding amount at the overlapping sections of the magnetic shield of the present invention is substantially greater.
