资源简介：
The present invention provides a thin-film sheet configured from a single layer or a plurality of layers less than or equal to three layers including at least a cellulose fine-fiber layer that includes regenerated cellulose fine fibers by 50 wt% or more， wherein the thin-film sheet achieves improvements in both thermal stability (thermal coefficient of linear expansion and retention of elasticity at high temperature) and sheet strength， and is characterized in that the requirements: (1) the specific surface area equivalent fiber diameter of fibers constituting the cellulose fine-fiber layer is 0.20-2.0 ??m inclusive; (2) the air impermeability is 1-100，000 s/100 ml inclusive; and (3) the film thickness is 2-22 ??m inclusive are satisfied. The present invention also provides a composite sheet， a composite prepreg sheet， a separator for power storage devices， etc.， that include the thin-film sheet.
