Abstract: The technology of this application relates to the field of filter technologies, and provides a common mode filter and a terminal device. The common mode filter includes a first winding and a second winding. A portion of the first winding and a portion of the second winding are formed, by rotating around a same axis, at a first coil layer. The other portion of the first winding and the other portion of the second winding are formed, by rotating around another same axis, at a second coil layer stacked with the first coil layer. At the first coil layer and the second coil layer, there is one turn of the second winding between each two adjacent turns of the first winding.
