1. A coil component comprising:
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,
wherein the first lead-out pattern connects the third terminal electrode and an inner peripheral end of the first planar spiral coil,
wherein the second lead-out pattern connects the fourth terminal electrode and an inner peripheral end of the second planar spiral coil, and
wherein the second insulating layer is thicker than the first insulating layer.
