PROBLEM TO BE SOLVED: To provide an assembled cell capable of appropriately maintaining a surface pressure added to each unit cell.SOLUTION: An assembled battery 10 is configured such that a plurality of chargeable/dischargeable unit cells 20 are arranged in a predetermined direction in a state of being electrically connected to each other and are restrained in a state of being added with load in an arrangement direction. The plurality of unit cells 20 include a positive electrode terminal 60 and a negative electrode terminal 62 which are electrically connected to a positive electrode and a negative electrode, respectively and arranged outside of a container 50. A buffer plate 40 which is restrained together with the unit cell 20 in a state of being added with the load in the arrangement direction is arranged in at least one of gaps between the arranged unit cells 20. The buffer plate 40 has a contact surface 42 which faces a container side wall 52 of the adjacent unit cell 20 and contacts the container side wall 52 of the unit cell when being restrained, and a forming portion 44 which allows the unit cell 20 to be deformed and a non-forming portion 46 which does not allow the unit cell 20 to be deformed are formed on the contact surface 42. |
