PROBLEM TO BE SOLVED: To provide a substrate incorporating a thin magnetic component, and to provide a switching power supply module employing it. SOLUTION: The substrate incorporating a thin magnetic component comprises a thin magnetic component having slit-shaped grooves provided in the front and back of a magnetic substrate, a through hole connecting the grooves in the front and back, a first conductor provided in the slit-shaped groove in the first major surface of the magnetic substrate, a second conductor provided in the groove in the second major surface, a connection conductor provided in the through hole, and a coil conductor formed of the first conductor, the second conductor and the connection conductor, and two insulator sheets on which a conductor pattern is formed wherein the thin magnetic component is arranged between the two insulator sheets and a portion of the coil conductor in the thin magnetic component is connected with a portion of the conductor pattern on the insulator sheet through a via hole. The switching power supply module comprises a substrate and a power supply IC wherein via holes are provided in the substrate to connect the front and back electrically, and the power IC is connected with the substrate incorporating a thin magnetic component through an electrode pattern provided on the first major surface.
