A reactor that is small and capable of adjusting a coupling coefficient is provided. A reactor includes a plurality of coils obtained by winding a winding wire and a core that magnetically couples the plurality of coils to each other. The plurality of coils is arranged parallel to each other such that the adjacent outer circumferential surfaces are opposed to each other. The core may include: (1) a plurality of magnetic leg portions around which the plurality of coils are respectively disposed and (2) a pair of coupling portions that are disposed at both end portions of the magnetic leg portions and that couple the end portions of the magnetic leg portions adjacent to each other. The reactor may further include a coupling coefficient adjustment means that adjusts a coupling coefficient between adjacent coils.
