Abstract
Provided is a separator for a nonaqueous electrolyte battery, which includes a porous substrate and an adhesive porous layer that is provided on at least one side of the porous substrate and contains an adhesive resin. The separator has a pore size distribution such that, as measured by a pore size distribution measurement test, the pore size at the maximum value of the maximum peak is within a range of 0.02 μm to 0.1 μm, and the pore size distribution range value ε defined as follows is 0.4 or less. The pore size distribution range value ε herein is a value calculated by the following equation from pore sizes D, D, and Dcorresponding to cumulative pore size distributions of 90%, 10%, and 50%, respectively:pore size distribution range value ε=(90−10 )/50.
