A power converter includes a plurality of semiconductor modules that have main body sections, each of the main body sections has a semiconductor element therein, and power terminals projected from the main body sections, and a plurality of bus bars that connect the power terminals of the semiconductor modules. At least one of the plurality of the bus bars are connecting bus bars which have a plurality of terminal connecting sections that connect the power terminals of the plurality of different semiconductor modules, and connecting sections that connect the terminal connecting sections. The entirety of each of the connecting bus bars is formed integrally. The terminal connecting sections and the connecting section of every connecting bus bar are provided alternately in the connecting bus bar, and disposed in substantially the same position in a projecting direction of the power terminals.
