1. A coil component, comprising:
a body;
first and second external electrodes disposed on the body and spaced apart from each other;
an insulating supporting member disposed in the body;
a first coil layer and a second coil layer disposed in the body;
a third coil layer and a fourth coil layer disposed on a first surface and a second surface of the insulating supporting member, respectively;
a first terminal portion disposed on the first surface of the insulating supporting member, spaced apart from the third coil layer, and connected to the first external electrode;
a first insulating layer covering the third coil layer and the first terminal portion;
a second terminal portion disposed on the second surface of the insulating supporting member, spaced apart from the fourth coil layer, and connected to the second external electrode; and
a second insulating layer covering the fourth coil layer and the second terminal portion, wherein the first and second coil layers are disposed on the first and second insulating layers, respectively, and
wherein the first terminal portion is connected to the first coil layer, the second terminal portion is connected to the second coil layer, the first coil layer is connected to the third coil layer, the third coil layer is connected to the fourth coil layer, and the fourth coil layer is connected to the second coil layer, through respective vias,
wherein the vias include a first via connecting the first terminal portion to the first coil layer; a second via connecting the second terminal portion to the second coil layer; a third via connecting the first coil layer to the third coil layer; a fourth via connecting the third coil layer to the fourth coil layer; and a fifth via connecting the fourth coil layer to the second coil layer.
