摘要： A separator paper is provided which simultaneously satisfies the requirements to have a high denseness that can prevent internal shortage due to such as the deposition of the zinc oxide dendrite accompanied by not adding mercury, and a high liquid impregnate properties that can improve heavy discharging properties. Said separator paper comprises a dense layer having a certain degree of denseness, and a liquid impregnate layer having a certain degree of liquid impregnate properties, said dense layer and said liquid impregnate layer being integrally laminated, and said dense layer being made by mixing alkali proof cellulose fibers which is applicable for beating with synthetic fibers such that said alkali proof cellulose fibers be included in the range of 20 to 80 weight % with the beating degree of 500 ml to 0 ml at CSF value, and said liquid impregnate layer being made by mixing alkali proof cellulose fibers with synthetic fibers such that said alkali proof cellulose fibers be included in the range of 20 to 80 weight % with the beating degree of more than 700 ml at CSF value.
