A reactor part includes at least a winding and a magnetic substance core, in which the core includes a pair of winding portions around each the winding is wound, and a non-winding portion around which no winding is wound, wherein a cross-sectional area in a direction orthogonal to a magnetic path of the non-winding portion of the core is made smaller than a cross-sectional area in a direction orthogonal to a magnetic path of the each of winding portions. |
