Abstract: The present disclosure relates to a lead storage battery comprising: a battery case having a cell chamber; a polar plate group provided in the cell chamber and having a separator, a positive electrode plate and a negative electrode plate, the positive electrode plate and the negative electrode plate being alternately stacked with the separator disposed therebetween; and an electrolytic solution accommodated in the cell chamber. The positive electrode plate and the negative electrode plate respectively have: electrode material filled portions comprised of electrode materials; current collectors supporting the electrode material filled portions; and ear portions provided on upper peripheral portions of the current collectors. The ear portion of the negative electrode has a surface layer containing Sn. When a total surface area of the electrode material filled portions is represented by S1 and an apparent total volume of the electrode material filled portions is represented by V1, S1/V1 is 8.9 cm -1 or larger.
