Abstract
Breakage of a ring core or a bobbin upon injection molding of molten resin is to be prevented in a method of manufacturing a reactor including the ring core. A reactor includes a ring core, a bobbin, a pair of coils, and a plastic cover. The bobbin includes a pair of cylinder portions, and flanges connecting ends of the cylinder portions. The reactor is manufactured by following processes. First protrusions that make contact with an inner circumferential surface of the ring core are provided on outer sides of the flanges along a cylinder axis direction. Second protrusions are provided at positions facing the corresponding first protrusions across the ring core are provided on a cavity surface of a mold that forms the plastic cover by injection molding. The plastic cover is formed by injecting molten resin into the mold while clamping the ring core by the first and second protrusions.
