PROBLEM TO BE SOLVED: To provide a laminated common mode choke array which can sufficiently reduce the influence of magnetic flux generated from one common mode choke coil on the other common mode choke coil and can be easily manufactured, and to provide a manufacturing method thereof. SOLUTION: The array has a non-magnetic insulating material layer 23 in which a plurality of non-magnetic insulating material sheets 23a-23d are laminated, and two pairs of common choke coils are formed by each of internal conductors 31-34 formed so as to be wound around individually the sheets 23a-23d; and a first and second magnetic material layers 22 and 24. The layer 23 is provided with magnetic cores 41-44 each formed in the magnetic direction of the layer 23 on the center position and both external positions of the winding of the two pair of common mode choke coils. The cores 41-44 are each formed of a magnetic material and have a magnetic permeability higher than that of each of the sheets 23a-23d. COPYRIGHT: (C)2006,JPO&NCIPI
