Abstract: A integrated inductor includes a first magnetic core, at least two second magnetic cores, and at least two windings. The first magnetic core includes a first surface and a second surface that are opposite to each other in a first direction. The second magnetic cores are disposed in the first direction on a side that is of the first surface and that is away from the second surface. The winding is wound around the first magnetic core and the second magnetic core. The second magnetic core includes a first part and a second part. Along the first direction and on a side that is of the first surface and that is opposite to the second surface, the first part is located between the winding and the first surface, and the second part is located on side that is of the winding and that is away from the first surface.
