The separator includes inorganic powder in an amount of 5 to 30% by weight and natural pulp in an amount of 3 to 20% by weight, and has a density of not less than 0.165 g/cm . The separator sufficiently suppresses the occurrence of electrical short circuits between the positive and negative electrode plates.
