摘要:
A magnetic shielding sheet for a wireless power reception module is provided. A magnetic shielding sheet for a wireless power reception module according to an exemplary embodiment of the present invention, which is applied to a wireless power reception module capable of a wireless power share (WPS) function and has an overall thickness of 150 μm or less. The magnetic shielding sheet includes a first sheet made of a magnetic material to shield a magnetic field, and a second sheet laminated as a monolayer on one surface of the first sheet by means of a bonding adhesive layer, wherein the second sheet is provided to have a smaller thickness than a thickness of the first sheet while having a saturation magnetic flux density twice or more than a saturation magnetic flux density of the first sheet.
