PROBLEM TO BE SOLVED: To provide a lead acid storage battery using a fiber mat separator which does not require jointing of separators in which a necessary jointing strength is hard to obtain, and suppresses short circuit between the electrode plates due to expansion of an active material and deterioration of battery capacity caused by this. SOLUTION: A fiber mat separator is folded into two and made in V-shape, and a separator which is folded in zigzag shape alternately so that it may be folded to nearly cross the folded line at right angles is formed, and an electrode plate of one polarity is arranged at a first separator overlapping part of which the upper part is open and the bottom part is closed. An electrode plate of the other polarity is arranged at a second separator overlapping part of which both the upper part and the bottom part are open, or at any one or both of the end faces of zigzag separators, and at least, a pair of the first separator overlapping part with no electrode plate and the second separator overlapping part with no electrode plate are arranged between the pair of electrode plates mutually opposed to each other.
