1. A coil component, comprising:
a body having a first surface and a second surface opposing each other, a first end surface and a second end surface connecting the first surface to the second surface and opposing each other, and a first side surface and a second side surface connecting the first end surface to the second end surface and opposing each other;
a wound coil disposed in the body, and having a plurality of turns and first and second lead-out portions exposed to the first end surface and the second end surface of the body;
a noise removing portion disposed in the body and spaced apart from the wound coil, and including a pattern portion having a first end portion and a second end portion spaced apart from each other and forming an open loop, and a third lead-out portion connected to the pattern portion and exposed to the first side surface of the body such that the noise removing portion is spaced apart from the second side surface of the body;
an insulating layer disposed between the wound coil and the noise removing portion; and
first to third external electrodes disposed on the first end surface, the second end surface, and the first side surface of the body, respectively, spaced apart from one another, and connected to the first to third lead-out portions, respectively,
wherein one of the plurality of turns of the wound coil has a line width greater than a thickness thereof.
