PROBLEM TO BE SOLVED: To provide a laminated common mode choke coil array where influence of magnetic flux generated respectively from a plurality of coil conductors on the other coil conductors has been reduced. SOLUTION: A non-magnetic insulating material layer 23 where a plurality of non-magnetic insulating materials are laminated and two common mode choke coils, each coil is formed of a first and a second internal conductors 31, 32 and a third and a fourth internal conductors 33, 34, are formed to each of the materials of these non-magnetic insulating materials, and a first and second magnetic material layers 21, 22 are provided. Above two common mode choke coils are provided adjacently with each other in the direction crossing in orthogonal the laminating direction. A magnetic flux generating conductor 40 for generating the inverted magnetic flux for preventing magnetic flux to that generated with the magnetic coupling of the common mode choke coil is provided between two common mode choke coils provided adjacently with each other.
