A coil component includes a body including a magnetic metal powder; an internal insulating layer buried in the body; an internal coil portion disposed on the internal insulating layer, and having turns of which cross-sectional areas increase towards the internal insulating layer from externally of the internal insulating layer; an external insulating layer covering the internal coil portion; an external coil portion disposed on the external insulating layer, and having a greater number of turns than a number of turns of the internal coil portion; a connection via penetrating through the external insulating layer and connecting the internal coil portion and the external coil portion; and an insulating film surrounding the internal insulating layer, the internal coil portion, the external insulating layer, and the external coil portion.
