COMMON MODE NOISE FILTER

PROBLEM TO BE SOLVED: To provide a common mode noise filter that ensures an attenuation amount of common mode noise.SOLUTION: The common mode noise filter is so constructed that first and second capacitor electrode layers 14, 15 are formed above first and second coils 12, 13, third and fourth capacitor electrode layers 16, 17 are formed below the first and second coils 12, 13, capacitor electrode layers connected to both end portions 12a, 12b of the first coil 12 are the first capacitor electrode layer 14 and the third capacitor electrode layer 16 positioned one above the other via the first and second coils 12, 13, and capacitor electrode layers connected to both end portions 13a, 13b of the second coil 13 are the second capacitor electrode layer 15 and the fourth capacitor electrode layer 17 positioned one above the other via the first and second coils 12, 13.
