Claim 11:
12. A coil component, comprising:
a body including a first surface and a second surface opposing each other, a third surface and a fourth surface connecting the first surface to the second surface and opposing each other, and a fifth surface and a sixth surface connecting the first surface to the second surface and opposing each other;
a support substrate disposed in the body;
a coil portion disposed on at least one surface of the support substrate and including first and second lead-out patterns exposed to the second and first surfaces of the body, respectively;
first and second external electrodes disposed on the second and first surfaces of the body, respectively, and connected to the first and second lead-out patterns of the coil portion, respectively; and
an insulating layer, formed as one integrated piece, disposed in a region of the at least one surface of the body other than a region in which the external electrode is disposed,
wherein an average roughness (Ra) of exposed surfaces of the first and second lead-out patterns in contact with the first and second external electrodes is less than an average roughness (Ra) of the second and first surfaces of the body in contact with the first and second external electrodes.
