Abstract
A magnetic material is pressure-molded using dies into a compact having an H-shaped cross section, constituted by a pair of flange parts that are facing each other and a web part connecting the pair of flange parts. Next, a cured product of the compact is turned around a rotational shaft passing through the center parts of the principal faces of the flange parts, and the web part is ground, to form a drum-type ground product having a pair of flange parts on both ends of a shaft part in a manner facing each other. Then, the ground product is heat-treated to obtain a drum core of a magnetic body. On the drum core, terminal electrodes are provided and a conductive wire with sheath is wound around the shaft part, after which an exterior part is given, to obtain a coil component.
