Abstract
In each of a plurality of semiconductor element groups of a power converter, a second semiconductor switching element and a third semiconductor switching element are shifted from each other in a second direction such that at least a portion of fins with which the second semiconductor switching element overlaps as viewed in a direction orthogonal to surfaces of coolers is different from fins with which the third semiconductor switching element overlaps as viewed in the direction orthogonal to the surfaces of the coolers.
