Abstract
The present invention provides a coil component provided with a magnetic core and a coil wound around the magnetic core. The coil component of the present invention is provided with an eddy-current generation member using any one of or any combination of a tape member using a conductive metallic foil, a thin film using a conductive metal material, a ribbon using a conductive metal material, a coated film using a conductive metal material, and a plate member using a conductive metal material. In a coil antenna adopting the coil component of the present invention, it is enabled to adjust the Q value to a desired value without increasing the direct current resistance value.
