    Abstract: A coil component includes a body, including a coil and a support member supporting the coil, and an external electrode disposed on an external surface of the body. The coil component includes a machined surface formed on a boundary surface between a portion of the support member, removed in the vicinity of a junction portion between the external electrode and the coil, and the remainder of the support member. A cavity, from which the portion of the support member has been removed, is filled with a magnetic material, or an insulating layer is disposed in the cavity.

    Abstract: A coil electronic component includes a magnetic body having a core part and a coil wound around the core part. The core part includes mixtures of magnetic metal material and resin. The magnetic body includes a first region adjacent to the coil and a second region adjacent to an outer surface of the magnetic body. Additionally, magnetic metal material of the first region adjacent to the coil has magnetic permeability higher than that of magnetic metal material of the second region adjacent to the outer surface of the magnetic body.

    Abstract: A coil component includes a body, a coil portion embedded in the body, and external electrodes electrically connected to the coil portion. The coil portion includes coil patterns having trenches formed in surfaces thereof. The trenches extend through a partial thickness of the coil portion, and are located at aligned locations in adjacent windings of the coil portion. A method of forming the coil component includes forming a mask pattern having a coil shaped opening and including a plurality of bridges extending across the coil shaped opening in the mask pattern.

    Abstract: An inductor includes a body including a coil, and a support member and external electrodes disposed on an outer surface of the body. The coil may include first and second coils, wherein the first coil does not coincide with a coil mirror-symmetric to the second coil, based on one surface of the body. This is due to the fact that exposure positions of lead portions of the first and second coils exposed to the outer surface of the body are different from each other.
