Claim 0:
1. A coil electronic component comprising:
a body including a support member having a through-hole, an internal coil comprising coil patterns disposed on one or more of upper and lower surfaces of the support member, and an encapsulant encapsulating the support member and the internal coil;
a first insulator disposed on a surface of each of the coil patterns; and
external electrodes disposed on an external surface of the body and connected to the internal coil,
wherein the coil patterns are wound in one direction and connected to each other, and among the coil patterns, an innermost coil pattern has a cross section composed of lower and upper cross sections, the lower cross section being rectangular, and the upper cross section at least partially including an inclined surface,
wherein a portion of the first insulator disposed between the innermost coil pattern and the through-hole comprises a protrusion extending over a portion of a surface of the innermost coil pattern opposite the support member, and
wherein the protrusion has a cross-section having a varying thickness.
