摘要	A method of manufacturing a coil component includes the steps of disposing a dummy metal layer on a base; laminating a base insulating resin on the dummy metal layer; exposing the dummy metal layer by disposing an opening part in the base insulating resin; disposing a spiral wiring on the base insulating resin and disposing a sacrificial conductor on the dummy metal layer in the opening part of the base insulating resin; enlarging the sacrificial conductor by plating by energizing the dummy metal layer; covering the spiral wiring and the sacrificial conductor with an insulating resin; exposing the sacrificial conductor by disposing an opening part in the insulating resin; forming a hole part by removing the sacrificial conductor by etching from the opening part of the insulating resin; and constructing the inner magnetic path of a magnetic resin by filling the hole part with the magnetic resin.
