Abstract
A coil electronic component includes a body including a plurality of insulating layers and coil patterns disposed on the insulating layers, and external electrodes formed on an external surface of the body and connected to the coil patterns. The plurality of insulating layers include a Ni—Cu—Zn based ferrite, and the Ni—Cu—Zn based ferrite has a content of Ni within a range from 5 to 15%, a content of Cu within a range from 5 to 10%, and a content of Zn within a range from 28 to 35% based on a mole ratio.
