摘要： The purpose of the present invention is to provide a polyolefin resin porous film, which is resistant to wrinkling in a transporting step in a high-temperature environment due to a high shrinkage stress, has superior coating suitability, maintains pore interconnectivity, and thus has superior air permeability. The polyolefin resin porous film of the present invention has a 1% modulus in the flow direction at 90° C. of 4.5 MPa or more and an air permeability of 800 sec/100 ml or less.
