PROBLEM TO BE SOLVED: To provide a separator excellent in durability and heat resistance and to provide a nonaqueous battery equipped with the same.SOLUTION: The separator includes a substrate material layer having a regenerated cellulose fiber that is fibrillated as a main component. On at least one surface of the substrate material layer, a polyamide imide fine fiber layer of an average fiber diameter of 10 to 1000 nm is laminated. The separator is integrated into a nonaqueous battery. |
