Claim 0:
1. A coil electronic component, comprising:
a support substrate;
a coil pattern disposed on the support substrate;
an encapsulant encapsulating at least portions of the support substrate and the coil pattern; and
external electrodes disposed externally on the encapsulant and connected to the coil pattern,
wherein the coil pattern includes a seed layer having a thickness of 1.5 μm or less and a plating layer disposed on the seed layer,
the plating layer includes a first plating layer, having a single-layer structure, disposed on the seed layer, a second plating layer covering the first plating layer, and a third plating layer disposed on an upper surface of the second plating layer, and
a thickness of the first plating layer is larger than the sum of a thickness of the second plating layer and a thickness of the third plating layer, where the thickness of the second plating layer is measured from the upper surface of the second plating layer and an upper surface of the first plating layer.
