Abstract: Provided is a polyolefin microporous membrane in which the membrane thickness is 1.0-17.0 ?m inclusive, the flexural modulus, which is the value of the flexural rigidity (gf×cm2/cm) in the longitudinal direction (MD) divided by the cube of the membrane thickness (?m), is 0.3 (?gf×cm2/cm)/?m3 to 1.5 (?gf×cm2/cm)/?m3 inclusive, and the basis weight-converted puncture strength is 70 gf/(g/m2) to 160 gf/(g/m2) inclusive.
