1. A reactor comprising:
a first winding;
a second winding;
a coupling core portion configured to form a coupling magnetic path, through which a magnetic flux generated by the first winding when the first winding is energized and a magnetic flux generated by the second winding when the second winding is energized pass, which magnetically couples the first winding and the second winding together, and which is aligned with a coupling plane that is a predetermined plane;
a first core portion configured to form a first magnetic path, through which the magnetic flux generated by the first winding when the first winding is energized passes and which is aligned with a first plane; and
a second core portion configured to form a second magnetic path, through which the magnetic flux generated by the second winding when the second winding is energized passes and which is aligned with a second plane,
the coupling plane intersecting at right angles with the first plane and the second plane.
