Abstract
A bus bar module is disposed over a plurality of housings to distribute DC power to smoothing capacitors and power conversion units. The bus bar module includes a first conductor and a second conductor. The first conductor is applied to either a first electrode or a second electrode of direct current. The second conductor is connected in parallel to the first conductor. The first conductor includes a first flat plate portion formed to have a first thickness in a cross section perpendicular to an extension direction. The second conductor includes a second flat plate portion having a cross section bent at a predetermined angle in a cross section perpendicular to the extension direction and formed with a second thickness thinner than the first thickness.
