<p>A choke coil which can be arranged tightly on an electronic circuit board (high-density mounting) and can be used over a wide band up to a microwave band while preventing oscillation due to magnetic coupling of choke coils. The choke coil comprises a combination of a coil section (1) formed by winding a conductor wire (2) covered with an insulation coating, rings (3) of width d disposed on the opposite end sides of the coil section (1) and having a center line in the same direction as a core (4) penetrating the coil section (1), and a rod-like core (4) of ferrite or ceramics inserted into the coil section (1). <IMAGE></p> |
