1. A reactor comprising:
a coil;
an annular magnetic core that forms a closed magnetic circuit when the coil is excited;
a plurality of divided reactors that constitute the reactor by being arranged in parallel; and
a holding member that holds the plurality of divided reactors in a state in which the divided reactors are arranged in parallel at a predetermined spacing,
wherein each of the divided reactors includes:
a coil unit that is formed of a wound wire and constitutes a part of the coil; and
a core unit that passes through the coil unit from one end of the coil unit to the other end and constitutes a part of the magnetic core,
the core unit has:
an inner core portion inserted through the coil unit, and
outer core portions that protrude from both ends of the coil unit and extend in a direction that intersects the inner core portion, and
the holding member includes:
attachment portions that are provided on an outer surface of opposing ends of the outer core portions of each of the divided reactors and fix the core units to an object to which the reactor is attached such that the core units are arranged in parallel.
