1. An electric power converter comprising:
a plurality of power modules that contains switching elements for electric power conversion and is stacked along a first direction;
a capacitor that is arranged adjacent to the plurality of power modules in a second direction perpendicular to the first direction; and
a positive bus bar and a negative bus bar that connect the plurality of power modules and the capacitor, wherein
each of the power modules has a positive terminal and a negative terminal provided on a side facing the capacitor, the positive terminal and the negative terminal being aligned in a third direction perpendicular to both the first direction and the second direction,
a leading end of the positive terminal and a leading end of the negative terminal are parallel to the side,
the capacitor includes a positive electrode on one end surface and a negative electrode on the other end surface in the third direction,
the positive bus bar includes a positive base plate that is joined to the positive electrode and a positive flange that is bent from the positive base plate in the third direction and is joined to the positive terminals of the plurality of power modules,
the negative bus bar includes a negative base plate that is joined to the negative electrode and a negative flange that is bent from the negative base plate in the third direction and is joined to the negative terminals of the plurality of power modules, and
the positive flange and the negative flange extend in directions away from the capacitor along the third direction.
