(57) [Problem] To obtain a porous molded article by a simple stretching condition and a production method which does not require an extraction step or the like. In addition, a film of a porous molded article having excellent opacity and free from solvent attack even when a commercially available offset ink for high quality paper is used is obtained. SOLUTION: Component (A) crystalline olefin resin 99 -40% by weight and component (B) weight average molecular weight of 1,000 A film based on a crystalline olefin-based resin composition containing 1 to 60% by weight of a polymer of a cyclic olefin having a glass transition point of 140 ° C. or higher and less than 10,000 is stretched to form fine pores Is obtained. |
