A coil component, includes: a body including an insulating substrate and a coil portion disposed on the insulating substrate, wherein the coil portion includes first and second upper patterns disposed on one surface of the insulating substrate to be spaced apart from each other, first and second lower patterns disposed on the other surface of the insulating substrate to be spaced apart from each other, and first and second vias each penetrating through the insulating substrate and disposed to be adjacent to each other. An area of one end portion of the first via, in contact with the first upper pattern is smaller than an area of one end portion of the second via, in contact with the second upper pattern, and an area of the other end portion of the first via is greater than an area of the other end portion of the second via.
