    Abstract: A coil component includes a body and a coil portion disposed in the body and including first and second lead-out portions. Recesses are disposed along edges of one surface of the body, and expose the first and second lead-out portions to internal walls and lower surfaces of the recesses. First and second external electrodes are disposed in the recesses, and are connected to the first and second lead-out portions. A third external electrode is disposed in the recesses, and is connected to a connection electrode disposed on side surfaces of the body and on another surface of the body opposite to the one surface. An external insulating layer covers the connection electrode, and has an opening exposing at least a portion of the connection electrode. A shielding layers is disposed on the external insulating layer and in the opening and connects to the connection electrode.
