WIPO Patent Application WO/2019/177341

A1

Provided are a large area type complex magnetic field shielding sheet and a wireless power transmission module comprising same. A large area type complex magnetic field shielding sheet according to an exemplary embodiment of the present invention is a large area type magnetic field shielding sheet having at least one of an overall width, an overall length and a diameter of 100 mm or more, the large area type complex magnetic field shielding sheet comprising: a main shielding layer arranged so that a plurality of ferrite block bodies having a predetermined area are adjacent to each other; and an auxiliary shielding layer made of at least one magnetic sheet having a predetermined area and laminated on one surface of the main shielding layer via an adhesive layer, wherein a boundary region between two ferrite block bodies arranged to be neighboring each other is arranged to be located in an inner region of the magnetic sheet so that a magnetic field leaking into a gap between the two ferrite block bodies is blocked by the magnetic sheet.
