Abstract: A module comprises a circuit board and an inductor. The circuit board has a facing surface and a rear surface which are located at opposite sides to each other in an up-down direction. The inductor has a magnetic core and a coil. The magnetic core is made of a soft magnetic metal material. The magnetic core has a facing surface and a radiating surface which are located at opposite sides to each other in the up-down direction. The facing surface of the magnetic core is arranged to face the facing surface of the circuit board in the up-down direction. The radiating surface of the magnetic core is arranged to be radiatable heat outward. The coil has a coil portion and a connection end. The coil portion winds, at least in part, the magnetic core. The connection end is connected to the facing surface of the circuit board.

Abstract: An inductor comprises a magnetic core and a coil. The magnetic core has a wound portion around which the coil is wound, and a peripheral portion. The magnetic core is formed from two or more preliminarily-formed-bodies which are pressure-molded in a state where the coil winds one or more preliminarily-formed-bodies which form the wound portion. The preliminarily-formed-bodies include at least one preliminarily-formed-body which forms the peripheral portion while not form the wound portion. Each of the preliminarily-formed-bodies is made of a mixture of flat magnetic powders and an organic binder so as to have a plate-like shape. The flat magnetic powders are oriented so as to be parallel to the preliminarily-formed-body.
