Abstract
A magnetic field shielding sheet is provided. The magnetic field shielding sheet according to an embodiment of the present invention is attached to a wireless power transfer antenna and a wireless communication antenna, and comprises: a shielding part made of a magnetic material so as to shield a magnetic field; and at least one eddy current-reducing pattern part which is formed in the shielding part to increase the resistance of the shielding part and thereby reduce the generation of eddy currents. The eddy current-reducing pattern part includes: a first eddy current-reducing pattern part formed to intersect with both the wireless power transfer antenna and the wireless communication antenna; and a second eddy current-reducing pattern part formed to intersect with the wireless communication antenna.
