Abstract: Provided are a separator for a nonaqueous cell that has air permeability and is small in thickness while maintaining strength properties; and a nonaqueous cell having this separator. The separator includes a fiber sheet in which a polyvinyl alcohol fiber is incorporated in a proportion of 30% or more by mass (based on the fiber sheet). The fiber has a fiber breaking temperature in heated water of lower than 100° C. and higher than 85° C.
