Bus bar and power supply device

Abstract

To provide a bus bar and a power supply device that reduce noise while suppressing cost and man-hours.SOLUTION: The busbar 10 includes a second capacitor connecting portion 17 to be connected to a second capacitor CD2 to be mounted on the board 3 and a second path portion 18 for electrically connecting the output-terminal connecting portion 13 and the second capacitor connecting portion 17. Such a second path portion 18 is configured to branch from the first path portion 16. Therefore, even when the output current picks up noise between the first capacitor connecting portion 14 and the output terminal connecting portion 13, the noise can be released to the substrate 3 side at the second capacitor connecting portion 17 via the second path portion 18 branched from the first path portion 16.SELECTED DRAWING: Figure 2
