Beschreibung
Zusammenfassung:	A magnetic field shielding sheet according to one embodiment is a magnetic field shielding sheet for an antenna that includes a hollow portion formed in a central region and having a predetermined area and a pattern portion surrounding the hollow portion. The magnetic field shielding sheet includes a sheet body formed as a multi-layer sheet in which a plurality of sheets are stacked in multiple layers with adhesive layers therebetween, wherein the sheet body is a multi-layer sheet in which the plurality of sheets having a relatively lower magnetic permeability while having a relatively higher surface resistance along a stacking direction are sequentially stacked.
