1. A reactor comprising:
a coil that includes a winding portion;
a magnetic core that includes an inner core portion that is disposed within the winding portion and an outer core portion that is disposed outside the winding portion;
a resin cover that houses at least a portion of the magnetic core; and
an adhesive portion that is provided so as to fill a gap between an outer circumferential surface of a housing portion of the magnetic core and an inner circumferential surface of the resin cover, and bonds the housing portion and the resin cover,
wherein the resin cover includes:
a flange portion that includes a surface that comes into contact with an end face of the winding portion and a through hole through which the inner core portion is inserted;
an outer cover portion that includes a housing portion that houses the outer core portion and an abutting portion that comes into contact with a portion of the flange portion, the portion being on a side opposite to the surface that comes into contact with the winding portion; and
a protruding portion that forms the gap between an outer circumferential surface of the outer core portion and an inner circumferential surface of the outer cover portion in a state in which the flange portion and the outer cover portion abut against each other.
