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.
