1. A reactor comprising:
a coil including a pair of winding portions arranged in parallel via a coupling portion;
a magnetic core including inner core portions arranged inside the winding portions and a pair of outer core portions arranged outside the winding portions;
a pair of holding members arranged so as to face end faces of the winding portions; and
a molded resin portion that covers at least a portion of outer peripheral surfaces of the outer core portions and fills spaces between inner peripheral surfaces of the winding portions and the inner core portions,
wherein the coil is constituted by a single continuous winding wire,
the coupling portion is formed by bending back a portion of the winding wire, and
one of the holding members on a side on which the coupling portion is arranged includes a recessed portion that houses the coupling portion and an inward projection that is arranged inside the coupling portion.
