PROBLEM TO BE SOLVED: To provide a method of manufacturing an electrode group and its manufacturing device, capable of improving productivity by reducing winding time and realizing reduction of failures by stable winding. SOLUTION: The electrode group structuring method is so structured that after a band cathode plate 1, a band anode plate 2 facing to the cathode plate 1 and two band separators 3 are pushed and pinched between a pair of main nip rollers 8, the electrode group is made to be wound in spiral around a winding core 7. The winding core 7 is rotated in such a state that a separator 3b on the winding core 7 side of the two separators 3, and the anode plate 2 are pinched by sub nip rollers 9, and, after the remaining separator 3a and the cathode plate 1 are wound, the main nip rollers 8 are released. Then, the cathode plate 1 is pressed and sent by using an auxiliary means with the anode plate 2 and the separator 3b pinched by the sub-nip rollers 9, it is wound around the winding core 7, and finally, the sub-nip rollers 9 are released for winding.
