Abstract: An assembled battery has a battery block configured by stacking a plurality of single batteries, and fixing components fixing the plurality of the single batteries. The fixing components include a pair of end plates disposed at both ends in a stacked direction of the plurality of the single batteries, and a metal band making the plurality of the single batteries in a compressed state by coupling end parts of the pair of the end plates each other. Each of the pair of the end plates has a peripheral part and a central part. The pair of the end plates respectively contact both end single batteries located at both ends in the stacked direction at the peripheral parts, and are respectively separated from both end single batteries at the central parts.
