    摘要: The present invention comprises a fused fiber layer, and a fine fiber layer adjacent to the fused fiber layer and comprising fine fibers and second fusible fibers, which are fused in the fine fiber layer, wherein part of the fine fibers are incorporated into the fused fiber layer, so that in determining a delamination strength between the fused fiber layer and the fine fiber layer, delamination occurs in the fine fiber layer and therefore the determination results in failure. The separator can be manufactured by preparing a fused fiber sheet, preparing a slurry containing fine fibers and second fusible fibers, scooping up the slurry with the fused fiber sheet, to thereby incorporate part of the fine fibers into the fused fiber sheet, and fusing the second fusible fibers in the fused fiber sheet. The separator is excellent in denseness and strength, despite its thinness, and can be used to produce alkaline batteries having a low electrical resistance. According to the process, the separator can be produced at a good productivity.
