<P>PROBLEM TO BE SOLVED: To provide a common mode filter capable of suppressing dispersion of characteristic impedance due to deviation of an interval between a pair of wires. <P>SOLUTION: The common mode filter includes: a drum core 10; a pair of wires 14, 15 wound around a winding core part 11 of the drum core by bifilar winding; terminal electrodes 16A, 16B provided on bottom surfaces of flange parts 12, 13 of the drum core; and connection electrodes 18A, 18B provided on the respective flange parts 12, 13 for connecting the terminal electrodes 16A, 16B and the wires 14, 15 respectively. The pair of wires 14, 15 are wound so that the same turns are stuck to each other and adjacent turns are separated from each other. A distance between terminal parts of the wires 14, 15 respectively spliced to the connection electrodes 18A, 18B is shorter than a distance between the terminal electrodes 16A, 16B. <P>COPYRIGHT: (C)2012,JPO&INPIT |
