Abstract: The manufacture method of a coil component includes the steps of bonding a dummy metal layer onto one face of a mounting base, stacking a base insulating resin on the dummy metal layer, stacking a first spiral wiring and a first insulating resin in this order on the base insulating resin to cover the first spiral wiring with the first insulating resin and stacking a second spiral wiring and a second insulating resin in this order on the first insulating resin to cover the second spiral wiring with the second insulating resin to thereby form a coil substrate, detaching the mounting base from the dummy metal layer in a bonding face between the one face of the mounting base and the dummy metal layer, removing the dummy metal layer from the coil substrate, and covering the coil substrate with a magnetic resin.

Abstract: An inductor component includes a composite body that includes a plurality of composite layers each including a composite material of an inorganic filler and a resin; and a plurality of spiral wires that each are stacked on the composite layer, the spiral wires each being covered with the other composite layer. The average particle diameter of the inorganic filler is equal to or smaller than 5 μm, the wire pitch of the spiral wires is equal to or smaller than 10 μm, and the interlayer pitch between adjacent spiral wires is equal to or smaller than 10 μm.

Abstract: 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.
