Abstract
A superconductor for magnetic field shielding which is characterized in that it includes at least one composite lamination including a thin film of the superconductor and a metal layer laminated with the thin film of the superconductor having a thickness not more than that obtained at the turning point where the magnetic field shielding effect of a single film of the superconductor changes from an abrupt increase to a gradual increase as the thickness of the superconductor film increases. This superconductor for magnetic field shielding has an extremely great magnetic field shielding effect even though the superconductor is in thin layers.
