摘要:
Provided are a large area type complex magnetic field shielding sheet and a wireless power transfer module including the same. A large area type complex magnetic field shielding sheet wherein at least one of an overall width, an overall length, and a diameter is 100 mm or more may include a main shielding layer arranged so that a plurality of ferrite block bodies each having a predetermined area are adjacent to each other, and an auxiliary shielding layer formed of at least one magnetic sheet having a predetermined area and laminated on the main shielding layer through an adhesive layer, wherein a boundary region between two ferrite block bodies disposed to be adjacent each other is disposed to be located in an inner region of the magnetic sheet and thus a magnetic field which leaks into a gap between the two ferrite block bodies is blocked by the magnetic sheet.
