Abstract: PROBLEM TO BE SOLVED: To provide a common mode noise filter which can attenuate not only common mode noise but also differential mode noise in a specific frequency band.SOLUTION: A common mode filter F1 consisting of spiral conductors 31-34 and a differential mode filter F2 consisting of spiral conductors 35 and 36 are laminated one on top of another on a magnetic substrate 11. The planar positions of the spiral conductors 31-34 are equal to each other, and the planar positions of the spiral conductors 35 and 36 are also equal to each other. The spiral conductors 35 and 36 respectively are formed in the same conductor layers as are the spiral conductors 31 and 32. These conductor layers are of underlayers close to the magnetic substrate 11. Since the spiral conductors 35 and 36 are formed in conductor layers close to the magnetic substrate 11, the frequency band of differential mode noise to be eliminated can be set exactly as designed.
