Abstract: Disclosed herein is a coil component that includes first and second magnetic members; a coil layer arranged between the first and second magnetic members, the coil layer including a plurality of conductor layers and a plurality of non-magnetic insulating layers, the conductor layers and the non-magnetic insulating layers being alternately laminated, the conductor layers being connected to each other via through holes formed in the non-magnetic insulating layers to form a coil pattern; a first external terminal covering one end of the coil pattern exposed to at least one of side surfaces of the coil layer without covering the first and second magnetic members; and a second external terminal covering other end of the coil pattern exposed to at least one of the side surfaces of the coil layer without covering the first and second magnetic members.
