Abstract: An object is to provide an output-noise reduction device that can prevent noise from an electronic device accommodated in a metal casing from being transmitted due to electromagnetic coupling. An output voltage is extracted to the outside through a conducting bar. A magnetic body core includes a through hole through which the conducting bar is inserted. A chip capacitor is mounted on a mounting board and connects between the output terminal VO and ground potential. A section from the output terminal VO to at least part of the chip capacitor mounted on the mounting board is isolated from the electromagnetic coupling from the electronic device. Thus, noise is prevented from being transmitted to the output terminal VO.

Abstract: A magnetic core that includes split magnetic cores provided with a plurality of gaps therebetween. The magnetic core is capable of suppressing the influence of a position shift of the split magnetic cores on magnetic characteristics. A first end face of a first split magnetic core faces a third end face of a second split magnetic core, with a first gap provided therebetween in a left-right direction. Further, a second end face of the first split magnetic core faces a fourth end face of a third split magnetic core, with a second gap provided therebetween in the left-right direction. The first to fourth end faces have a mutually parallel relationship.
