Zusammenfassung:	A common mode noise filter is provided, and comprises a first transmission structure and a second transmission structure. At least one first inductance is connected in series between a first signal input end and a first signal output end of the first transmission structure. At least one second inductance is connected in series between a second signal input end and a second signal output end of the first transmission structure. Two first capacitors are connected in series between the first signal input end and the second signal input end, and connected to a first node together. A first common mode noise suppression unit is connected between the first node and a ground, and comprises a second capacitor and a first lossy element connected to the second capacitor in series or parallel. The first common mode noise suppression unit can absorb a common mode noise via the first lossy element.
