PROBLEM TO BE SOLVED: To suppress positional displacement of a battery cell in a stacking mode being pressurized in stacking direction for cell fastening.SOLUTION: A first end plate 14 is set on a cell stacking pallet 100. The cell stacking pallet 100 includes a cell bottom surface reference rail 112 and cell side surface reference rail 114 in two rows, and the cell bottom surface reference rail 112 and the cell side surface reference rail 114 are extended from the first end plate 14 that has been set. Then, respective battery cells 12S are sequentially stacked and set on the cell stacking pallet 100 in an inclination posture in which a cell upper end side separates from the first end plate 14 and inclined toward the cell bottom surface reference rail 112, and a second end plate 15 is stacked and set on the stacked battery cell 12S. After that, pressurizing is made from the side of the second end plate 15 in the cell stacking direction for stacking. |
