1. A reactor comprising:
a coil having a wound part;
a magnetic core having an inner core part disposed inside the wound part and an outer core part disposed outside the wound part; and
a holding member holding an end face of the wound part in an axial direction and the outer core part,
wherein the holding member is a frame-shaped body having a through hole into which an end portion of the inner core part in the axial direction is inserted, and
the outer core part has an inward surface opposing the inner core part, an outward surface on an opposite side to the inward surface, and a plurality of peripheral surfaces joining between the inward surface and the outward surface,
the reactor comprising a core coupling member coupling the outer core part and the inner core part,
wherein the core coupling member has:
a supporting piece supporting the outward surface of the outer core part; and
an engaging leg piece extending from the supporting piece and passing through the holding member, and
the engaging leg piece has a distal end engaging a peripheral surface engaging part formed on a peripheral surface of the inner core part.
