SOLUTION: The bus bar structure includes multiple conductor plates and band-shaped insulating sheet members. Predetermined planar areas of the sheet members within an identical plane are sandwiched between the conductor plates; and the other planar areas different from the predetermined planar areas are exposed to the outside. A protruded portion is formed on at least one side face of the conductor plates and a bent portion is formed in the exposed surfaces of the sheet members so that the protruded portion is positioned inside the bent portion. The power conversion device uses the bus bar structure as an output conductor. COPYRIGHT: (C)2009,JPO&INPIT
