Abstract

Disclosed herein is a coil component that includes a plurality of conductor layers including first, second, third, and fourth conductor layers stacked one on another in this order. First and third planar spiral coils are formed in the first and third conductor layers. A second planar spiral coil is formed in the second and fourth conductor layers. A pattern width of the second planar spiral coil formed in the second conductor layer is smaller than that of the second planar spiral coil formed in the fourth conductor layer, or a pattern width of each of the first and third planar spiral coils formed in the third conductor layer is smaller than that of each of the first and third planar spiral coils formed in the first conductor layer.
