PROBLEM TO BE SOLVED: To miniaturize a noise filter, further to improve workability and reproducibility when assembling and wiring are performed and to eliminate the variation of the electric performance, part arrangement, etc., for every product. SOLUTION: Various electronic parts 3 are provided on a printed board 4 and the parts 3 are made to be located at the lower part of a terminal block 5. Further, a fixing fixture 10 that fixes the printed wiring board 4 to the terminal block 5 are also provided on the printed board 4. Thus, it is possible to miniaturize this noise filter drastically, also to rapidly improve workability and reproducibility and to eliminate the variation of the electric performance, part arrangement, etc., for every product.
