A manufacturing method for a substrate embedded with integrated inductor includes: providing a bearing plate; manufacturing a first conduction copper column on the bearing plate; arranging a first dielectric layer on the bearing plate which covers the first conduction copper column; opening the first dielectric layer to form a first opening; filling a magnetic material at the first opening; grinding the first dielectric layer so that surfaces of the first conduction copper column and the magnetic material are flush with a surface of the first dielectric layer; removing the bearing plate, etching a metal layer on the surface of the first dielectric layer to form a package substrate; arranging a first circuit layer and a solder mask layer on an upper surface and a lower surface of the package substrate; and forming a window in the solder mask layer corresponding to the first circuit layer.
