The magnetic field shielding sheet, according to an exemplary embodiment of the present invention, which is applied to a combo-type antenna unit that includes at least two antennas using different frequency bands of magnetic fields, comprises: a first sheet layer that includes a metal component that shields a first frequency band of a magnetic field and concentrates the magnetic field in a designated direction; a second sheet layer that shields a second frequency band of a magnetic field and concentrates the magnetic field in a designated direction; and a micro-piece separation and oxidation preventing member provided on a side surface of the first sheet layer in order to prevent a micro-piece from being separated from the side surface of the first sheet or to prevent the side surface from being oxidized. According to the present invention, by virtue of the micro-piece separation and oxidation preventing member provided on the side surface of the first sheet layer, it is possible to prevent the side surface from being oxidized and to prevent short-circuiting due to particles."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Magnetic field shielding sheet and wireless power transmitting module including same","description":"A magnetic field shielding sheet and a wireless power transfer module that includes the same are provided.
