This application provides a planar transformer and a switching power adapter. The planar transformer includes a PCB winding and two magnetic cores. The two magnetic cores wrap two sides of a winding body of the PCB winding to form a closed magnetic loop. A first group of welding points is disposed on a primary-side wire side of the PCB winding, and a second group of welding points is disposed on a secondary-side wire side of the PCB winding. The planar transformer is directly welded to an external circuit board by using the first group of welding points and the second group of welding points. In this way, no pin needs to be welded on the PCB winding board. In addition, the planar transformer can be vertically installed on the external circuit board by using the first group of welding points and the second group of welding points.
