1. A reactor, comprising:
a coil including a winding portion; and
a magnetic core including an inner core portion to be arranged inside the winding portion and an outer core portion to be arranged outside the winding portion;
wherein:
the magnetic core includes:
a communication hole penetrating through the outer core portion and leading to the inner core portion; and
a coupling shaft made of a composite material filled into the communication hole, the coupling shaft coupling the inner core portion and the outer core portion,
wherein the coupling shaft includes a retaining portion to be hooked to an inner peripheral surface of the communication hole in an axial direction of the coupling shaft, and
the composite material is obtained by dispersing a soft magnetic powder in a resin.
