    Abstract: The coil electronic component includes: a body including a support member having a through-hole, an internal coil 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; and external electrodes disposed on an external surface of the body and connected to the internal coil. The internal coil has coil patterns including an innermost and an outermost coil patterns. A portion of cross section of the innermost coil pattern has a different width than a remainder of the cross section of the innermost coil pattern.
