Abstract
A power supply module includes a substrate, a switching control IC and a coil. The coil includes a plurality of metal posts, first ends of which are mounted on a first surface of the substrate, wiring conductors that are in conductive contact with the first ends of the metal posts, and post connection conductors that are in conductive contact with second ends of the metal posts. The power supply module further includes a magnetic core that strengthens magnetic flux generated by the coil, and a sealing resin that seals the metal posts and the magnetic core.
