Provided is a reactor such that the overall size of the reactor can be made more compact than conventional reactors, while maintaining the performance thereof. The reactor, in one embodiment thereof, comprises a molded coil formed by arranging in parallel two coils electrically connected in series and combining the two coils by molding the outer sides in the diameter direction thereof with resin, and two U-shaped iron cores, the insertion sections at both sides of each iron core being inserted into a respective coil in the axial direction of said coil from one side of said coil so as to face a respective insertion section of the other iron core so that the insertion sections are linked in a track-like form with gaps interposed therebetween to form a core as a whole. The molded coil is formed to be roughly a hexahedron shape, each iron-core has an outside-coil section by which both sides of insertion sections inserted in the coils are joined together from outside the coils, and a resin layer containing magnetic metal, which is comprised of resin containing magnetic metal, which in turn is a mixture of magnetic metal powder and binder resin, is formed on the outer faces of the outside-coil sections of the iron cores. |
