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.
