This reactor (DA) comprises: a coil (1A); an upper core member (21A) and a lower core member (22A) that encase the coil (1A); and a convex part core member (22b) that is positioned at the core of the coil (1A). The coil (1A) is configured by coiling a band-shaped conductor member such that the latitudinal direction of the conductor member follows the axial direction of the coil (1A). The one interior surface, of the upper core member (21A), that faces one of the end parts of the coil (1A) in the axial direction thereof, and the other interior surface, of the lower core member (22A), that faces the other of the end parts of the coil (1A) in the axial direction, are parallel in a region that at least covers the one of the end parts and the other of the end parts of the coil (1A). One of the end parts of the convex part core member (22b) is positioned within an aperture part (APA), which is formed upon the upper core member (21A), with a gap (GA) left between the circumference face of the one of the end parts and the circumference face of the aperture part (APA). The reactor (DA) thus provides a reactor that has comparatively high inductance, with low levels of loss and noise. |
