PROBLEM TO BE SOLVED: To provide a common mode noise filter capable of improving connection reliability to an external electrode without significantly varying a direct current resistance value or a characteristic impedance.SOLUTION: In a common mode noise filter according to the present invention, a first spiral conductor 24 is connected to first and second lead-out conductors 26, 27, and a second spiral conductor 25 is connected to third and fourth lead-out conductors 28, 27. The first spiral conductor 24 is magnetically coupled with the second spiral conductor 25, and first to fourth external electrodes 23a-23d are connected to the first to fourth lead-out conductors 26-29, respectively. Also, the first and second spiral conductors 24, 25 and the first to fourth lead-out conductors 26-29 are formed on different insulator layers, and thickness of the first to fourth lead-out conductors 26-29 is larger than thickness of the first and second spiral conductors 24, 25. |
