Abstract:
A drum-type magnetic body includes: a pair of flange parts that are facing each other; and a shaft part connecting the pair of flange parts, wherein an outer periphery of a cross section of the shaft part in a direction orthogonal to an axis of the shaft part has an oval shape constituted by a pair of parallel straight parts and a pair of arc parts connecting end parts of the pair of parallel straight parts, and the flange parts each have an outer principal face running orthogonal to the axis of the shaft part, and the pair of parallel straight parts are running in parallel with a longitudinal direction of the principal face of the flange part.
