Abstract: The case housing a plurality of cells is divided, by a circuit board provided at the same sides of the cells, into a housing space housing the cells and an exhaust duct for releasing a gas from the vents of the cells to outside the case. The vents of the cells communicate with the exhaust duct through openings formed in the flat plate. The exhaust duct is divided into a first space and a second space by a partition provided between the flat plate and an external plate of the case. The first space communicates with the second space through holes formed in the partition.

Abstract: A battery-affixing frame member includes a body plate section and duct-forming members. The duct-forming members are affixed to one surface side of the body plate section and are combined with the body plate section to form gas discharge ducts. The gas discharge ducts are used to discharge gas discharged from the inside of battery modules. The battery-affixing frame member is used to form a battery-affixing member for integrally affixing the battery modules together, the battery modules being arranged on the other surface side of the body plate section.
