Abstract: The present invention is a method for producing a stretched film comprising stretching an unstretched film that is formed using a hydrogenated dicyclopentadiene ring-opening polymer at a temperature of 95 to 135° C. and a stretching ratio of 1.2 to 10, followed by heating at a temperature of 150 to 220° C. Since the thus-obtained stretched film has excellent transparency and low coefficient of linear expansion, the stretched film is suitable for not only use in optical applications but also use for electronic materials.
