PROBLEM TO BE SOLVED: To provide a compact and lightweight reactor.SOLUTION: A reactor 1 comprises: a pair of coils 3, 4 arranged in parallel; and a circular core 2, and is mountable on a mounting surface. The core has coil winding parts 23, 24 covered in the respective coils, and exposed parts 21, 22 exposed without being covered in the coils. The exposed parts are joined to entire end faces of the coil winding parts, and have first projection portions 21A, 22A projecting beyond an extension surface of outer peripheral surfaces of the coil winding parts away from the mounting surface, and second projection portions 21C, 22C projecting toward the mounting surface. The first projection portions are shaped so as to project most in an area including a middle region of the pair of coils along the direction of juxtaposition, and the second projection portions have a flat surface facing the mounting surface. |
