Abstract: A common mode noise filter includes: a plurality of insulator layers; and a first coil conductor, a second coil conductor, a third coil conductor, a fourth coil conductor, a fifth coil conductor, and a sixth coil conductor. A first interval I1 measured in an upward/downward direction from an upper surface of the first coil conductor to a lower surface of the third coil conductor, a second interval I2 measured in the upward/downward direction from an upper surface of the fourth coil conductor to a lower surface of the sixth coil conductor, and a third interval I3 measured in the upward/downward direction from the lower surface of the third coil conductor to the upper surface of the fourth coil conductor satisfy I1
