Abstract:
The assembled battery (1) is provided with: multiple battery cells (10) stacked along a predetermined direction; a cell case (20, 30) for accommodating the battery cells (10); a constraint plate (60) attached to the cell case (20, 30); and a case (300) for accommodating the cell case (20, 30). The cell case (20, 30) has openings (22, 32) at both ends in the predetermined direction. The constraint plate (60) applies pressure, through one of the openings (22, 32), to the battery cells (10) from one end side in the predetermined direction.
