A coil component includes a body having one surface and the other surface facing each other; an insulating substrate embedded in the body, and having one surface substantially perpendicular to the one surface of the body; a coil portion disposed on the one surface of the insulating substrate, and including a coil pattern layer having a coil pattern and a lead-out pattern extending from the coil pattern and exposed from the one surface of the body; an insulating layer disposed on the one surface of the insulating substrate to cover the coil pattern layer; and first and second external electrodes arranged to be spaced apart from each other on the one surface of the body and respectively connected to the lead-out pattern. A thickness of the lead-out pattern is greater than a thickness of the coil pattern, and less than a thickness of the insulating layer.
