Abstract
A reactor includes a coil having a winding portion; a magnetic core; and a case. The magnetic core includes a plurality of core pieces forming a closed magnetic circuit. The core pieces include two outer core pieces having a portion disposed outside the winding portion. The case includes a first and a second opposing faces are respectively opposed to outer edge faces of the outer core pieces, and a case inclined surface provided on at least one of the first and the second opposing faces. The case inclined surface is inclined such that a distance between the first opposing face and the second opposing face decreases from an opening side of the case toward an inner bottom face of the case, and a core inclined surface on the outer edge face side of the outer core piece is in surface contact with the case inclined surface.
