PROBLEM TO BE SOLVED: To provide a method for manufacturing a spiral plate group capable of ensuring a capacity as designed by suppressing generation of a gap between a sheet-shaped separator and a reinforcing separator at the initial time of winding. SOLUTION: In the case of manufacturing a spiral plate group by winding after arranging a positive/negative plate 31, 32 in surfaces 33a, 33b respectively of a sheet-shaped separator 33, a reinforcing separator 34 is arranged in a part of the sheet-shaped separator where at least a winding start end part 31b of the positive plate 31 is positioned, and a part R1 arranging this reinforcing separator is formed in curved shape. |
