Abstract:
To provide a reactor capable of reducing amplitude when an assembly is vibrated.SOLUTION: A reactor includes: a coil having a pair of wound portions arranged in parallel; a magnetic core; a holding member which defines mutual positions of the coil and the magnetic core; a casing that houses an assembly that includes the coil, the magnetic core, and the holding member; and a sealing resin that fills up the casing. The casing is provided with a bottom plate, a side wall, and an opening. The assembly is housed in the casing so that an axial direction of each of the wound portions is along in a depth direction of the casing.
