A reactor device is provided with a first core, a second core, and a plurality of coils. The first core and the second core each have a plate-shaped base portion, and two leg portions that extend from one plate surface of the base portion and are disposed in an alignment direction. The first core and the second core are disposed such that the leg portions of the first core and the leg portions of the second core extend toward each other, and the leg portions of the first core are apart from the leg portions of the second core. Each of the coils is wound around both of one corresponding thereto of the leg portions of the first core and one corresponding thereto of the leg portions of the second core. Each of the base portions has narrow-width sections which are disposed at both ends of the base portion in the alignment direction and each have an end surface that is flush with a side surface corresponding thereto of the leg portion in the plate thickness direction of the base portion, and a wide-width section which is disposed between both the narrow-width sections and has a dimension in a width direction orthogonal to the plate thickness direction and the alignment direction larger than the maximum dimension in the width direction of the leg portion. |
