A lead storage battery 1 comprises an electrode plate group 7 in which a positive electrode plate 9 and a negative electrode plate 10 are stacked with a separator 11 being interposed therebetween, and a battery case 2 that houses the electrode plate group 7. The separators 11 adjacent to each other through the target electrode plate, which is either the positive electrode plate 9 or the negative electrode plate 10, are connected to each other on the target electrode plate side of a bottom portion 31 of the battery case 2. The separator 11 has a base portion 21 and a rib 22 protruding from the base portion 21. The rib 22 has a bottom rib portion 22a arranged between the base portion 21 and the bottom portion 31. The battery case 2 has a shape in which the base portion 21 does not reach the bottom portion 31 when the electrode plate group 7 is inserted into the battery case 2.
