Claim Text:
1. A power conversion apparatus comprising: a filter capacitor accumulating direct-current power; a semiconductor device module performing a switching operation that converts the direct-current power accumulated in the filter capacitor to alternating-current power; and a laminated bus bar electrically connecting the filter capacitor and the semiconductor device module, wherein the laminated bus bar comprises: a bus bar in which a plurality of conductors are laminated through an insulator; an external laminate material coating an external surface of the bus bar; connection portions electrically connected to the semiconductor device module and the filter capacitor; and a heat radiating portion in which the external laminate material is not provided and a conductor of the bus bar is exposed to air, and wherein every surface of the exposed conductor of the heat radiating portion is formed to be along a vertical direction.
