The present invention prevents the occurrence of deviation and the formation of folds and creases when shaping a separator, is capable of ensuring more stable shaping properties, and is capable of achieving a reduction in cycle time. The present invention is provided with: a step in which a separator (4) is zigzaggedly folded; a step in which positive electrode plates (5) and negative electrode plates (6) are alternately inserted into respective valley grooves of the separator to form a stacked body in which the positive electrode plates (5) and the negative electrode plates (6) alternately overlap each other; and a step in which guide rods (21) are extracted from inside the respective valley grooves, and electrode groups are subsequently produced in the stacked body. A separator of a length that is withdrawn during the zigzag folding is stored in advance. In the zigzag folding step, when the stored separator is to be withdrawn at the upstream side to a zigzag folding means, the stored separator is fed towards the zigzag folding means, the position of the separator is restricted at the downstream side of the zigzag folding means, and conveyance of the separator is guided. Furthermore, in the zigzag folding step, a force is exerted which opposes the advancement of the separator moving towards the zigzag folding means. |
