An inductive module includes an electrically insulating basic substrate unit having opposite first and second trace-forming sides, a ferromagnetic core unit embedded in the basic substrate unit and having horizontal sides substantially parallel to and respectively spaced apart from the first and second trace-forming sides, and a coil unit. The coil unit includes first and second conductive vias respectively formed in the basic substrate unit adjacent to vertical sides of the core unit, and respectively spaced apart from the vertical sides, and first and second conductive traces, each of which is disposed on a corresponding one of the first and second trace-forming sides, and interconnects electrically a corresponding pair of the first and second conductive vias. The conductive traces and the conductive vias of the coil unit cooperate to form an electric current path that substantially winds around the core unit.
