PROBLEM TO BE SOLVED: To provide a common mode noise filter that can be used in a resonance circuit without any problem, while downsizing the product.SOLUTION: A common mode noise filter 11 is constituted by connecting a pair of first and second cross capacitors Cc, Cc with a common mode choke coil 12. The common mode choke coil 12 is constituted by winding a pair of conducting wires 12b, 12c around a core 12a, and a pair of inductors Ls, Ls are formed. In the drawing, the first cross capacitor Cc on the upper side is connected between the input side of the inductor Ls formed by one conducting wire 12b and the output side of the inductor Ls formed by the other conducting wire 12c. In the drawing, the second cross capacitor Cc on the lower side is connected between the output side of the inductor Ls formed by one conducting wire 12b and the input side of the inductor Ls formed by the other conducting wire 12c. |
