A wireless charging module is provided. In a wireless charging module according to an exemplary embodiment of the present invention, at least one wireless charging coil unit is fixed on one surface of a shielding sheet. The shielding sheet comprises: a ferrite sheet which is made by a sheet member having a predetermined area and shields an object from a magnetic field generated by a wireless high frequency signal; and position maintaining members which are attached to upper and lower surfaces of the ferrite sheet, respectively, such that even when the ferrite sheet is broken by an external impact, positions of pieces of the broken ferrite sheet can be maintained. According to the present invention, even when the ferrite sheet is broken into a plurality of pieces, positions of the pieces can be maintained by the position maintaining member which is a film member having an adhesive layer. Therefore, a preferable charging efficiency for which the wireless charging module is initially designed can be maintained since characteristics of the ferrite sheet barely change. |
