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.
