PROBLEM TO BE SOLVED: To provide a cylindrical sealed lead-acid battery preventing coming off of an active material, winding slippage, and short circuit. SOLUTION: The cylindrical sealed lead-acid battery has an electrode group formed by winding a positive plate and a negative plate through a separator. The separator is a pile of three separators, two separators coming in contact with the surfaces of the electrode plates prevent the coming off of the active material, and the separator positioned in the middle prevents short circuit.
