Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a separator which helps increase the capacity of an alkaline secondary battery.SOLUTION: The separator is composed of a porous material having a large number of continuous pores. In a pore diameter distribution curve measured by a mercury porosimeter, a difference between the maximum pore diameter of the separator at which the cumulative frequency of mercury volumes integrated from a large pore diameter side reaches 10% and the minimum pore diameter at which the cumulative frequency reaches 90% is 30 μm or less. |
