Abstract
A coil component having high inductance while suppressing core loss is obtained. The coil component includes a coil and a magnetic core. The magnetic core has a laminated body in which soft magnetic layers are laminated. Micro gaps are formed in the soft magnetic layers. The soft magnetic layers are divided into at least two or more small pieces by the micro gaps. A structure made of Fe-based nano-crystals is observed in the soft magnetic layers.
