A reactor (1) according to the present invention is provided with: a plurality of winding wires (2), a coupling core (3) and an inductor core (4). The plurality of winding wires (2) are wound around the coupling core (3), thereby forming a closed magnetic path for coupling, which magnetically couples the plurality of winding wires (2) to each other. The inductor core (4) comprises: main parts (411, 421); first projection parts (412, 422) which respectively protrude from one end of the main parts (411, 421); and second projection parts (413, 423) which respectively protrude from the other end of the main parts (411, 421). The first projection parts (412, 422) and the second projection parts (413, 423) are magnetically coupled to the coupling core (3). The inductor core (4) forms a closed magnetic path for inductor, together with a portion of the coupling core (3), around said portion one wiring wire (2) among the plurality of winding wires (2) being wound.
