Abstract
Provided is a magnetic field shielding sheet including: an amorphous ribbon which is formed into a plurality of pieces; a cover layer which is bonded on one surface of the amorphous ribbon; a double-sided tape which is adhered on the other surface of the amorphous ribbon; and an adhesive film which is filled in gaps between the plurality of pieces, to prevent water from penetrating into the gaps. Accordingly, the amorphous ribbon is prevented from being oxidized with no result of causing an appearance problem and lowering shielding performance, due to oxidizing of the amorphous ribbon.
