摘要：
A polyolefin microporous membrane is capable of achieving a low shutdown temperature while keeping air permeation resistance sufficiently low, and a method produces the polyolefin microporous membrane. The polyolefin microporous membrane has, when a temperature is raised to 230° C. at a temperature rise rate of 10° C./min in differential scanning calorimetry (DSC), a ratio of a melting heat quantity (ΔH
