An electric power conversion device includes a capacitor package. The capacitor package includes a first positive electrode bus bar that is connected to a positive electrode of the inverter circuit unit and connected to a smoothing capacitor. The capacitor package also includes a second positive electrode bus bar that is connected to a positive electrode on a battery side of the converter circuit unit and connected to the another smoothing capacitor. On a first side thereof the negative electrode bus bar directly overlaps the entire first positive electrode.
