<p>PROBLEM TO BE SOLVED: To reduce a noise current without increasing a size of a magnetic body even when a large current is applied.SOLUTION: In a noise absorption device 10 provided to a main circuit W, the main circuit W is divided into a high-impedance circuit 20 and a low-impedance circuit 30 so as to have the same current amount in a low-frequency region and to have a biased current amount in a high-frequency region. The high-impedance circuit and the low-impedance circuit are arranged so as to be opposed to each other in an annular magnetic body.</p> |
