PROBLEM TO BE SOLVED: To provide a common mode choke coil capable of effectively reducing in particular a high frequency band noise with a simple structure and realizing further downsizing.SOLUTION: In the common mode choke coil, a first coil 2 at one end part 1a side of a rod-like core 1 and a second coil 3 separated from the first coil 2 by an interval at the other end part 1b side are wound in a direction in which a differential mode signal current to flow therethrough and a common mode noise current is removed, respectively. |
