A reactor comprises: a magnetic core (20); a coil (30); a first cooling member (40, 60); a second cooling member (41, 61); a first sealing resin portion (50); and a second sealing resin portion (51). The first sealing resin portion and the second sealing resin portion, by being filled in a gap between a heat radiating surface of the first cooling member and the magnetic core and a gap between a heat radiating surface of the second cooling member and the magnetic core, are formed to expose side surfaces (20c, 20d) of the magnetic core while sealing a lower surface (20b) of the magnetic core and an upper surface (20a) of the magnetic core. A cross sectional shape of the magnetic core in a plane orthogonal to the flow of magnetic fluxes produced upon energization of the coil is a flattened shape of which a dimension in a perpendicular direction with respect to the same direction as a direction in which the first cooling member and the second cooling member are arranged is greater than a dimension in the same dimension. |
