| Summary: | A common mode choke coil includes two laminated coil conductors, a first magnetic substrate arranged on one of the coil conductors, and a second magnetic substrate arranged on the other coil conductor. When it is assumed that a distance from a conductor center of the one coil conductor to the surface of the first magnetic substrate is designated as A, a distance from a conductor center of the other coil conductor to the surface of the second magnetic substrate is designated as B, and a distance from the conductor center of the one coil conductor to the conductor center of the other coil conductor is designated as C, C<(A+B)/2 is satisfied. Accordingly, because a difference in the distances between the magnetic substrates and the coil conductors becomes relatively small, a leakage inductance due to the difference in the distance decreases, and the cut-off frequency with respect to a differential mode signal can be increased. |
