Abstract: A reactor includes a plurality of windings, a coupling core, and an inductor core. A coupling core configured to form a coupling closed magnetic circuit that magnetically couples the plurality of windings, the plurality of windings being wound around the coupling core; and. An inductor core, which includes a main part, a first projection part projecting from one end of the main part, and a second projection part projecting from another end of the main part, and each of the first projection part and the second projection part is magnetically connected to the coupling core. The inductor core forms an inductor closed magnetic circuit together with a part of the coupling core around which one winding of the plurality of windings is wound.
