The purpose of the invention is to improve the durability of an assembled battery. The assembled battery comprises: a plurality of flat batteries having a pair of wide width surfaces facing in a thickness direction of a battery container at the surface of the battery container; a holding member for making the wide width surfaces of adjacent flat batteries face each other to stack the flat batteries and holding the flat batteries while applying a predetermined compressive force thereto; and an exterior insulating film for covering the outer circumference of the battery container except for parts of the wide width surfaces. The holding member has a spacer provided between the wide width surfaces of adjacent flat batteries facing each other and touching non-protected portions of the wide width surfaces at touching portions, said non-protected portions being not covered with the exterior insulating film. |
