Abstract
Disclosed herein is a coil component that includes first, second, third, and fourth terminal electrodes; a first planar spiral coil formed on a substrate, the first planar spiral coil having an outer peripheral end connected to the first terminal electrode; a second planar spiral coil stacked on the first planar spiral coil through a first insulating layer, the second planar spiral coil having an outer peripheral end connected to the second terminal electrode; and first and second lead-out patterns stacked on the second planar spiral coil through a second insulating layer. The first lead-out pattern connects the third terminal electrode and an inner peripheral end of the first planar spiral coil. The second lead-out pattern connects the fourth terminal electrode and an inner peripheral end of the second planar spiral coil. The second insulating layer is thicker than the first insulating layer.
