摘要

Provided is a reactor which can inhibit the movement of a coil caused by vibrations during operation while improving radiation performances. A reactor provided with a coil formed by winding a winding wire, and a magnetic core having an inner core part disposed inside the coil and an outer core part which is linked to the inner core part and which forms a closed magnetic path with the inner core, wherein: the outer core part is provided with a side main body which functions as a magnetic path; the side main body has an opposing surface including an inner core part opposing region which faces the inner core part, and a coil opposing region which faces the end surface of the coil; and an adhesive layer is provided, said adhesive layer being disposed at least between the inner core part and one portion in the circumferential direction of the inner circumference surface of the coil or between the end surface of the coil and the coil opposing region to secure the coil with at least the inner core part or the outer core part.
