Abstract
The present invention provides a coil component includes: a coil section having a through hole and composed of a plurality of ring sections formed of a metallic flat plate disposed in a plane, connected to each other at ring connecting sections, having slits formed by cutting part of the ring sections, and bent at the ring connecting sections and placed one on top of another, terminals connected to the coil section, and a package member covering the coil section and projecting the terminals therefrom. With this structure, the coil component operates in a high-frequency region, ensuring an inductance and infinitesimal direct-current resistance while being adaptable to a large current, and can be miniaturized.
