<P>PROBLEM TO BE SOLVED: To provide a low-loss, low-noise reactor having relatively large inductance. <P>SOLUTION: A reactor DA includes a coil 1A, an upper core member 21A and a lower core member 22A encapsulating the coil 1A, and a convex piece core member 22b disposed at the core portion of the coil 1A. The coil 1A is constituted by a belt-shaped conductor member whose width direction is wound along the axial direction of the coil 1A. In an area at least covering each end portion of one end portion and the other end portion of the coil 1A, one internal face of the upper core member 21A, facing opposite to the one end portion of the coil 1A in the axial direction, is parallel to the other internal face of the lower core member 22A, facing opposite to the other end portion of the coil 1A in the axial direction. One end portion of the convex piece core member 22b is disposed in an aperture APA formed on the upper core member 21A, with a gap GA between the peripheral surface of the one end portion and the peripheral surface of the aperture APA. <P>COPYRIGHT: (C)2012,JPO&INPIT |
