Abstract
A sheet for shielding a room, conductive cables, magnetic recording media, inside shield rooms and other objects, from the effects of a magnetic field. The sheet is used as a magnetic shield by wrapping it around the objects or areas which need shielding from the effects of a magnetic field. The sheet is composed of a flexible magnetic shielding sheet of less than 100 &mgr;m thick and is made from alloys which have magnetic shielding capability such as alloys of Fe—Ni series and the like. The Fe—Ni series alloy contains 30 to 85 wt % Ni and also at least either one kind of Mo or Cu in the content of less than 8 wt %. Other than these, alloys of Fe—Cr—Al series and Fe—Co—V series are included. The magnetic shielding sheet,may also include an adhesive layer, film, or paper, laminated on at least one surface of the sheet. The sheet thus obtained is easily applicable for winding around the surface of a communication cable, making an envelope or a bag for keeping a floppy disk (FD), or shielding a room.
