Abstract
A noise suppressor capable of preventing degradation in an attenuation characteristic by a parasitic component so as to obtain a favorable attenuation characteristic is provided. The noise suppressor includes a first winding wire disposed on a first current-carrying wire and a series circuit including a capacitor and a second winding wire which are connected to each other in series. The first winding wire and the second winding wire are magnetically coupled to each other. The inductance xL of the whole second winding wire is smaller than the inductance LL of the whole first winding wire (xL<LL). Moreover, it is desirable that the inductance xL of the whole second winding wire is equal to or smaller than the inductance LLper turn in the first winding wire (xL≦LL).
