1. A bus bar module comprising:

  • a plurality of bus bars that are arranged at intervals from each other in an arranging direction of electrode terminals of each of electrode terminal groups arranged in a row on a battery module formed of a plurality of battery cells, and are physically and electrically connected to the electrode terminals to be connected; and

    a flexible flat conductor that includes conductive portions each electrically connected to each of the bus bars, and insulating holding members each holding each of the conductive portions and each of the bus bars, and gives flexibility to the conductive portions and the holding members, the flexible flat conductor being formed in a flat shape, whereinthe conductive portions include respective extension sections that extend in the same direction from each other in the arranging direction and are disposed at intervals from each other, and respective electric connecting portions that are each an end part on an extending direction side of the extension sections and are each electrically connected to the bus bar to be connected in a direct or indirect manner,the holding members each include a cover that covers each of the conductive portions so as to collectively hold the conductive portions, and a bus bar holder for each of the bus bars, the bus bar holder projecting from the cover and individually holding each of the bus bars,the flexible flat conductor includes conductor connection areas for respective bus bars, the conductor connection areas each including the bus bar and the electric connecting portion electrically connected to each other, and a connection area that connects the conductor connection areas adjacent in the arranging direction to each other, andeach of the connection areas is formed in a mountain fold shape so as to expand and contract in the arrangement direction, and is formed so as to reduce a difference in rigidity between the connection areas.
