PROBLEM TO BE SOLVED: To provide an electrode plate for lead acid battery the life performance of which can be enhanced without reducing the discharge capacity, and to provide a lead acid battery the life performance of which is enhanced by using the electrode plate as a positive electrode plate.SOLUTION: In an electrode plate for lead acid battery composed at least of a collector, and an active material group connected electrically with the collector, the active material group contains fiber having at least one bend. The fiber having a bend is a fiber of frizz shape, and the crimp rate, represented by percentage of the difference of length when the fiber is uncrimped and the original length before uncrimping to the elongated length, is 5-25%. A lead acid battery having excellent life performance using the electrode plate as a positive electrode plate is also provided. |
