Abstract
A reactor includes a coil and a magnetic core. The coil includes one winding portion. The magnetic core includes a middle core part, two side core parts and two end core parts. The middle core part has a part to be arranged inside the winding portion. Each of the two side core parts is arranged side by side with the middle core part outside the winding portion. Each of the two end core parts is arranged to connect the middle core part and the two side core parts outside end parts of the winding portions. The magnetic core has a first region and a second region having a higher relative magnetic permeability than the first region. The first region includes two corner parts constituted by the middle core part and each of the two end core parts. The second region includes a base end region and a projecting region.
