PROBLEM TO BE SOLVED: To provide a multilayer common mode filter in which the attenuation peak in the frequency characteristics of attenuation for common mode noise is shifted to the high frequency side, the depth of attenuation peak is large, and impedance reduction can be suppressed.SOLUTION: A first conductor layer 25 adjoining a first coil C1 in the opposite direction of a pair of magnetic materials 5A, 5B (hereinafter, referred to "the opposite direction" ) has first and second conductors 26, 27 arranged to overlap a part of the first coil C1, when viewing from the opposite direction, and spaced apart from each other. A second conductor layer 28, adjoining the second coil C2 in the opposite direction, has third and fourth conductors 29, 30 arranged to overlap a part of the second coil C2, when viewing from the opposite direction, and spaced apart from each other.SELECTED DRAWING: Figure 2 |
