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.

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 μm or more.

Abstract: A coil component includes a support member, an internal coil supported by the support member, and external electrodes connected to the internal coil. The external electrodes may each include a first layer coming into contact with the internal coil and a second layer disposed on a surface of the first layer. The first layer may serve as a buffer layer for improving a contact property between the internal coil and the external electrode. The second layer may be disposed to come into at least partial contact with a first end portion of the support member and a second end portion of the support member.
