Beschreibung
Zusammenfassung:	A magnetic shield which comprises: a plurality of metallic cylinders connected to each other in the axial direction thereof, each of the plurality of cylinders having at one end thereof an engaging section for receiving an end of an adjacent metallic cylinder to be connected thereto; and a film of a composite oxide superconducting material containing a CuxOy-radical, formed on the entire inner surface of each of the plurality of cylinders, including the inner surface of the engaging section thereof. The above-mentioned magnetic shield can easily be scaled up and has a high magnetic shielding effect.
