This application discloses a coil module, a wireless charging transmitting apparatus, a wireless charging receiving apparatus, a wireless charging system, and a terminal. The module includes a first planar coil winding and a second planar coil winding. A first coil of the first planar coil winding includes a first outer side part and a first inner side part. An end part of the first coil of the first planar coil winding includes an end part of the first outer side part and an end part of the first inner side part. A first coil of the second planar coil winding includes a second outer side part and a second inner side part. An end part of the first coil of the second planar coil winding includes an end part of the second outer side part and an end part of the second inner side part. The end part of the first outer side part is connected to the end part of the second inner side part. The end part of the second outer side part is connected to the end part of the first inner side part. This application can effectively reduce a circulating current loss in the first planar coil winding and the second planar coil winding, and improve wireless charging efficiency of the coil module.
