PROBLEM TO BE SOLVED: To provide a common mode filter array capable of improving the impedance of a coil and reducing crosstalk between coil pairs. SOLUTION: A laminate 1 included in the common mode filter array CF1 is formed by laminating a first external layer 60, a first filter section 10, an intermediate section 50, a second filter section 30 and a second external layer 70 in this order. The first and second filter sections 10, 30 include pairs of coils L11 and L12, and L21 and L22 each magnetically coupled to blank bodies 20, 40 composed of a non-magnetic body, respectively. The coils L11, L12 and L21, L22 include coil conductors 14-17 and 34-37. The intermediate section 50 is composed of a magnetic body. The first and second external layers 60, 70 also are composed of magnetic bodies. The thickness T<SB>0</SB>of the intermediate section 50 in the laminating direction of the laminate pairs is thicker than thicknesses T<SB>1</SB>, T<SB>2</SB>of the first and second external layers.
