1. A reactor, comprising:
a coil including a pair of winding portions arranged in parallel;
a magnetic core to be 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 to be 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 constituted by a rectangular frame body configured to surround the assembly, and an opening provided on a side opposite to the bottom plate portion,
the pair of winding portions are arranged in a parallel direction orthogonal to the bottom plate portion,
the side wall portion includes a pair of short side portions and a pair of long side portions,
the short side portion or the long side portion includes a groove portion continuously provided from the opening side toward the bottom plate portion side and open inward of the case, and
when the assembly is accommodated into the case, a nozzle for injecting resin is inserted between the assembly and the side wall portion along the groove portion.
