Abstract
A coil electronic component includes a body, in which a coil portion is embedded, including a plurality of magnetic particles, and an external electrode connected to the coil portion. Among the plurality of magnetic particles, at least a portion of magnetic particles include a first layer, disposed on a surface of a magnetic particle among the magnetic particles, and a second layer disposed on a surface of the first layer. The first layer is an inorganic coating layer containing a phosphorus (P) component, and the second layer is an atomic layer deposition layer.
