Abstract
A resin-mold core includes right and left leg portions, and a yoke portion interconnecting those. The resin-mold core includes a magnetic core, and a mold component having the magnetic core embedded therein by molding. Openings where the magnetic core in the mold component is exposed are formed in multiple faces of the mold component that are upper, lower, front, rear, and right and left faces. A part of the yoke portion of the resin-mold core corresponding to a location where terminals are drawn to the exterior of the core from coils attached to the outer circumferences of the leg portions of the core has no opening formed in the multiple faces of the mold component. Positioning members to coaxially align the leg portions of the opposing resin-mold core are formed in abutting faces of the leg portions of the resin-mold core.
