PROBLEM TO BE SOLVED: To connect a noise elimination filter to a terminal plate connected to an output side of an electric power circuit in a housing of an electric power device at a position close to the outside of the housing.SOLUTION: A terminal block 2 is provided on a back 6 of a housing 4 in which an electric power circuit is arranged, and inward ends of terminal plates 20 and 20 where the terminal block 2 penetrates to the inside and the outside of the housing 4 are connected to substrates 40 and 42 where the power circuit in the housing 4 is constituted. Unnecessary signals together with output current are output from the substrates 40 and 42 to the terminal plates 20 and 20. A noise elimination filter is constituted on a substrate 44 arranged very closely opposite the terminal block 2 in the housing 4. The terminal plates 20 and 20 penetrate the substrate 44, and the terminal plates 20 and 20 are connected to predetermined positions of the noise elimination filter on the substrate 44 through piece-shaped bodies 48 and 48.SELECTED DRAWING: Figure 1 【課題】 電源装置の筐体内において筐体の外部に近い位置で、電源回路の出力側に接続されている端子板に、ノイズ除去フィルタを接続する。【解決手段】 電源回路が内部に配置されている筐体４の背面６に端子台２が設けられ、端子台２を筐体４の内外に貫通した端子板２０、２０の内方端が筐体４内の電源回路が構成されている基板４０、４２に接続されている。端子板２０、２０には、基板４０、４２から出力電流と共に不要信号が出力される。筐体４内における端子台２の直近にこれと対向して配置された基板４４上にノイズ除去フィルタが構成されている。端子板２０、２０が基板４４を貫通し、端子板２０、２０は、片状体４８、４８を介して基板４４上のノイズ除去フィルタの所定位置に接続されている。【選択図】 図１
