Abstract: A coil component includes a body portion including a magnetic material, and a coil portion disposed in the body part. The coil portion includes a first coil pattern layer having a planar spiral pattern, an insulating layer formed of an insulating resin embedding at least a portion of the first coil pattern layer, and a second coil pattern layer disposed on the insulating layer and having a planar spiral pattern. The insulating layer includes a core material disposed between the first and second coil pattern layers, and a thickness of a lower region of the insulating layer disposed below the core material is greater than a thickness of an upper region of the insulating layer disposed above the core material.

Abstract: A coil component includes a body having a coil part disposed in the body. The coil part may include: a first coil pattern formed on one surface of the insulating layer; and a second coil pattern including an external pattern formed on the other surface of the insulating layer. The second coil pattern may further include an embedded pattern embedded in the insulating layer and the external pattern may be disposed on the embedded pattern. The coil component can have improved low direct current resistance characteristics and inductance.

Abstract: A thin film-type inductor includes a body including a support member, a coil disposed. on at least one surface of the support member, and a filler embedding the support member on which the coil is disposed, and an external electrode disposed. on an external surface of the body. An insulating layer is not disposed on an edge portion of the support member and the edge portion is in direct contact with a filler. The insulating layer is only disposed on an upper surface of the coil to conform to a surface of the coil.
