A device designed to reduce temperature rise in its control board, and to be compact. The device includes a switching element(4); a coil(9); a smoothing capacitor (10); an electrical connection member(7) for electrically connecting the switching element(9) with the smoothing capacitor (10) and the coil(9); a control board(1) that mounts a control element; a control signal line(5) for electrically connecting the switching element(4) with the control board(1); and a switching element placing portion(6) for placing the switching element (4) thereon. The electrical connection member(7) is arranged between the switching element(4) and the control board(1); the smoothing capacitor(10) and the coil(9) are arranged, with respect to the electrical connection member(7), on a side of the switching element(4); and end surfaces of the smoothing capacitor(10) and the coil(9) are positioned, with respect to the electrical connection member(7), apart from a plane where the switching element(4) and the switching element placing portion(6) are adjoined together.
