Claim:
1. A magnetic field shielding sheet for a digitizer, the magnetic field shielding sheet comprising: a magnetic field shielding main sheet that is disposed on a rear surface of the digitizer to thus prevent affecting the digitizer; and a magnetic field shielding sub-sheet that is laminated in a dual on at least one of four side edges of the magnetic field shielding main sheet, to prevent the digitizer from being affected by a magnesium frame inside a portable terminal device, wherein the magnetic field shielding main sheet is made of an amorphous alloy or a nanocrystalline alloy, and comprises a shielding layer made of a plurality of pieces by flakes, a cover layer adhered to one surface of the shielding layer, and a double-sided tape adhered to the other surface of the shielding layer, and wherein the magnetic field shielding sub-sheet is formed of a band shape having a certain width and is attached to a periphery of the magnetic field shielding main sheet while having the same structure as that of the magnetic field shielding main sheet.
