1. A reactor, comprising:
a coil including a pair of winding portions arranged in parallel;
a magnetic core arranged inside and outside the winding portions;
a case configured to accommodate an assembly including the coil and the magnetic core; and
a sealing resin portion filled into the case,
wherein:
the case includes a bottom plate portion, the assembly being placed on the bottom plate portion, a side wall portion configured to surround the assembly, and an opening facing the bottom plate portion, the opening having a rectangular planar shape,
the pair of winding portions are arranged such that a parallel direction of the pair of winding portions is orthogonal to the bottom plate portion,
the reactor includes a supporting member to be arranged along a short side direction of the opening, and
the supporting member includes an end portion stopped in contact with a facing inner surface of the side wall portion of the case such that the end portion of the supporting member is directly supported on the case while exerting a pressing force in a direction perpendicular to the facing inner surface of the side wall portion of the case.
