PROBLEM TO BE SOLVED: To provide a common mode noise filter capable of enhancing the removal characteristic of a common mode noise.SOLUTION: A common mode noise filter includes a laminate 11 in which a plurality of insulator layers 12 are laminated, three coil conductors 13, 14, 15 provided inside the laminate 11, and an external electrode 23 connected to the coil conductors 13, 14, 15 provided in the laminate 11. Each of the three coil conductors 13, 14, 15 is configured in a spiral form to have one or more turns. The outer shape of the plane perpendicular to the winding axis of each coil conductor is a rectangular shape comprising long sides and short sides, and provided on one insulator layer 12. The long sides of two coil conductors out of the three coil conductors 13, 14, 15 are arranged to confront one another, and the short sides of the two coil conductors and the long sides of the other coil conductor are arranged to confront one another.SELECTED DRAWING: Figure 1 |
