摘要： A separator for alkaline batteries, which exhibits excellent strength, dimensional stability and chemical stability in an electrolyte solution, while having high shielding properties, high liquid holding properties and low resistance. A separator for alkaline batteries, which is used for the purpose of separating a positive electrode active material and a negative electrode active material from each other, and holding an electrolyte solution, and which is obtained by stacking and integrating a fiber layer A that has a density of 0.52-0.62 g/cm3 and a thickness of 25-35 μm and a fiber layer B that has a density of 0.40-0.50 g/cm3 and a thickness of 25-35 μm, so that the entirety of the separator has a density of 0.45-0.57 g/cm3 and a thickness of 50-70 μm.
