COIL COMPONENT AND ELECTRONIC CIRCUIT

摘要

Provided are a coil component capable of preventing internal residence of air bubbles after encapsulated with a resin and an electronic circuit incorporating such coil component. The coil component (10) includes: a columnar core having a flange portion (210) which is formed to have a diameter larger than that of a shaft portion having a coil wound therearound; and an annular core having an opening (110) through which the columnar core is inserted, the perimeter of the inner flange face of the flange portion (210) being configured by externally disposed regions (211,212,213,214) which are positioned outside the inner face of the opening (110) in the radial direction, and internally disposed regions (215,216,217,218) which are positioned inside the inner face of the opening (110) in the radial direction.
