An object of the present invention is to provide a norbornene-based polymer film having good peelability and high productivity. A norbornene polymer containing 0.01 to 2.00 mol% of a repeating unit (1) derived from a norbornene compound represented by the following general formula (I) among all repeating units. [Chemical 1] (Wherein R 1 , R 2 , R 3 and R 4 each independently represents a hydrogen atom, a halogen atom, a methyl group, or an aryl group which may have a substituent, provided that R 1 , At least one of R 2 , R 3 and R 4 represents the aryl group.) [Selection figure] None |
