Abstract: A coil assembly, an electronic device, and a wireless charger. The coil assembly includes a first coil winding, a second coil winding, and a circuit board. The second coil winding is stacked with the first coil winding. A plurality of first terminals and a plurality of second terminals are disposed on the circuit board. Each first terminal is connected to each second terminal by using a cable. In a plurality of cables used to connect the plurality of first terminals and the plurality of second terminals, at least two cables are changed to different line layers in a cross region through first vias to be disposed in a crossed manner.
