PROBLEM TO BE SOLVED: To provide: a noise reduction device whose compactness is achieved without deteriorating noise reduction effect; a power supply device with the noise reduction device; and a core arrangement method for the noise reduction device.SOLUTION: A noise component transmitted from an AC-DC conversion circuit 20 to power source lines 30a and 30b and a noise component transmitted from the AC-DC conversion circuit 20 to a frame ground line 31 are different from each other. The power source lines 30a and 30b are wound around a core 60, and the frame ground line 31 is wound around a core 70. A core support member 80 allows penetration directions of the through holes 60a and 70a respectively for the cores 60 and 70 to be parallel to each other, and also fixedly supports the cores 60 and 70 so that the cores 60 and 70 are spaced apart by a predetermined distance with respect to the penetration directions of the cores 60 and 70. |
