| 摘要 | A nonaqueous electrolyte secondary battery separator is a porous film containing a polyolefin as a main component. The nonaqueous electrolyte secondary battery separator (i) has a phase difference of 80 nm or less with respect to light having a wavelength of 590 nm in a state where the nonaqueous electrolyte secondary battery separator is impregnated with ethanol and (ii) has a porosity of 30% to 60%. | ||
