SHIELDING FILM, COIL ASSEMBLY, AND WIRELESS CHARGING DEVICE

A shielding film includes a first film layer. The first film layer includes a first conductive part and a first insulating part, and the first insulating part penetrates the first conductive part in a thickness direction of the first film layer. Under electromagnetic influence of a first electromagnetic field, a first eddy current is formed in the first film layer, and a loop of the first eddy current is located in the first conductive part, so that the first eddy current has relatively high current intensity. Under electromagnetic influence of a second electromagnetic field, a second eddy current is formed in the first film layer, and a loop of the second eddy current passes through the first insulating part, so that current intensity of the second eddy current can be reduced.
