Claim Text:
1. A common mode filter comprising: a first inductor having a first winding number, wherein the first inductor comprises a first input terminal of a first coil of the first inductor, a first output terminal of the first coil, and a first intermediate terminal branching from an intermediate portion between the first input terminal and the first output terminal; a second inductor facing the first inductor and having a second winding number, wherein the second inductor comprises a second input terminal of a second coil of the second inductor, a second output terminal of the second coil, and a second intermediate terminal branching from an intermediate portion between the second input terminal and the second output terminal; a first capacitor having one end connected to the first intermediate terminal, and another end connected to a ground; a second capacitor having one end connected to the second intermediate terminal, and another end connected to the other end of the first capacitor and the ground; a third capacitor having one end connected to the first output terminal, and another end connected to the ground; and a fourth capacitor having one end connected to the second output terminal, and another end connected to the other end of the third capacitor and the ground.
