Abstract: A coil electronic component includes a magnetic body that includes a substrate and a coil part. The coil part includes patterned insulating films disposed on a surface of the substrate and a plating layer formed between the patterned insulating films by plating and having a thickness greater than or equal to its width measured parallel to the surface of the substrate. The plating layer may be formed in a single plating operation, and may have a thickness of 200 m or more.

Abstract: A coil component includes a body in which a coil portion is disposed, and external electrodes connected to the coil portion. The body includes metal particles formed of an Fe-based nanocrystal grain alloy, and the Fe-based nanocrystal grain alloy has one peak or two peaks in a differential scanning calorimetry (DSC) graph, and when the Fe-based nanocrystal grain alloy has the two peaks, a primary peak is smaller than a secondary peak, where the primary peak is at a lower temperature than the secondary peak.
