PROBLEM TO BE SOLVED: To provide a reactor in which a space between a core and a coil is the most easily filled with resin, and the core is easy to handle in manufacturing the reactor.SOLUTION: The reactor is equipped with: the coil 10 that has a pair of coil elements 10A, 10B that are mutually connected in a parallel state with windings wound spirally; inner core parts 22 that are inserted into both of the coil elements 10A, 10B and form a part of a ring-shaped core 20; and exposed core parts 24 that are exposed from each coil element 10A, 10B and form a remnant of the ring-shaped core 20 by connecting the inner core parts 22 together. The reactor is equipped with an outer resin part that covers at least a part of an assembly body 1A of the coil 10 and the core 20. It becomes easy to fill a space between the coil 10 and the core 20 with resin, and fragmenting and the like during handling, is prevented by notched corners 24g formed on connecting points of inner end surfaces 24f that face an end surface of the coil and adjacent surfaces (side surfaces 24s) that are connected to the inner end surfaces 24f, among the exposed core parts 24. |
