1. A power conversion device comprising:
a power module;
a plurality of capacitor elements each having an element body portion, a first electrode provided on a first surface of the element body portion, and a second electrode provided on a second surface of the element body portion on an opposite side to the first surface;
a first busbar connecting the first electrode of each of the plurality of capacitor elements and the power module to each other; and
a second busbar connecting the second electrode of each of the plurality of capacitor elements and the power module to each other, wherein
the power module is disposed so as to be opposed to a side surface of the element body portion of only one of the capacitor elements, and
one or each of the first busbar and the second busbar has, as a connection member connecting the power module and a corresponding one of the first electrode or the second electrode to each other, an opposed plate-shape portion opposed only to an opposed portion of the side surface of the element body portion opposed to the power module,
wherein each of the first busbar and the second busbar are connected to a side of the power module power module facing the plurality of capacitor elements.
