PROBLEM TO BE SOLVED: To provide a lead acid storage battery which is low in failure rate of assembly and excellent in large current discharging performance and life performance while an element is retained under high pressure. SOLUTION: In the lead acid storage battery equipped with an electrode plate group (element) obtained by laminating positive and negative electrode plates through a separator, the separator is pressed in advance, and the battery is equipped with the electrode plate group (element) satisfying the relationship of 1<T<SB>1</SB>/d≤2 and T<SB>2</SB>/d≥0.8, (wherein T<SB>1</SB>is the thickness (mm) of the separator; T<SB>2</SB>is the thickness (mm) of the separator after pressed; and d is the interval (mm) between the positive and negative electrode plates).
