Claim 14:
15. A coil electronic component comprising:
a support member;
a spiral internal coil comprising coil patterns disposed on the support member;
a first insulator disposed on a surface of each of the coil patterns;
a second insulator disposed on surfaces of the coil patterns that do not come in contact with the first insulator including a surface of the coil pattern opposite the support member;
a body encapsulating the support member and the spiral internal coil; and
external electrodes disposed on external surfaces of the body and connecting the spiral internal coil,
wherein the coil patterns include an innermost coil pattern having a smallest diameter and an outermost coil pattern having a longest diameter,
a cross section of the coil patterns is defined by a thickness and a width,
a portion of the innermost coil pattern adjacent the support member has a width larger than a portion of the innermost coil pattern farther from the support member such that the portion of the innermost coil pattern with the larger width has a smaller thickness than that of the innermost coil pattern, and
wherein the first insulator disposed between the outermost coil pattern and an external surface of the body perpendicular to the support member comprises a protrusion extending over a portion of the second insulator disposed on the surface of the outermost coil pattern opposite the support member.
