PROBLEM TO BE SOLVED: To provide a low-cost coil component, and also to reduce leak magnetic flux by materializing stable direct-current superposition characteristics with simple structure. SOLUTION: By forming a mold with the mixture of soft magnetism metallic powder and resin, sufficient direct-current superposition characteristics are made possible, so that the circumference of an open magnetic circuit component comprising a drum type magnetic body core 1 and winding 3 wound around the core 1a of the drum type magnetic body core 1 may be made into a closed magnetic circuit.
