PROBLEM TO BE SOLVED: To provide a noise filter device having a high current capacity while suppressing a rise in the price.SOLUTION: The noise filter device includes a first noise filter and a second noise filter. The first noise filter is formed by disposing a plurality of first coils corresponding to phases of an AC power source separately in a plurality of areas of an annular first core in a circumferential direction. The second noise filter is formed by disposing a plurality of second coils corresponding to phases of the AC power source separately in a plurality of areas of an annular second core in a circumferential direction. In the noise filter device, the first noise filter and the second noise filter are overlapped in a vertical direction in the state where the plurality of first coils and the plurality of second coils with the same phase face each other, one end of the plurality of first coils and one end of the plurality of second coils with the same phase are coupled with each other, and another end of the plurality of first coils and another end of the plurality of second coils with the same phase are coupled with each other. |
