1. A coil component comprising:
a body;
a support substrate disposed in the body;
a coil portion including coil patterns, lead patterns, and extension patterns and disposed on the support substrate, the lead patterns being exposed to outside of the body, the extension patterns connecting the coil patterns to the lead patterns; and
external electrodes disposed on the body and contacting the lead patterns,
wherein each of the lead patterns has an inner portion adjacent to one of the extension patterns, an outer portion adjacent to one of the external electrodes, and a middle portion disposed between the inner portion and the outer portion,
a width of the middle portion is larger than a width of the inner portion and smaller than a width of the outer portion, and
in a cross-section perpendicular to a winding axis of the coil patterns, each of the lead patterns is wedge-shaped with sharp ends at the corresponding outer portion, and inner angles defined at the sharp ends of each lead pattern are acute angles that face each other.
