    Abstract: PROBLEM TO BE SOLVED: To provide a method of manufacturing a cyclic olefin-based polymer, wherein the production of a gel by the cyclic olefin-based polymer provided by the easy method is inhibited and the production of the gel is highly suppressed even if ring-opening (co)polymerization of a monomer such as dicyclopentadiene prone to produce the gel by the ring-opening (co)polymerization in particular; to provide the cyclic olefin-based polymer with a low gel content provided by the manufacturing method; and to provide a method of manufacturing a film and an oriented film from the cyclic olefin-based polymer, in the present invention. SOLUTION: The method of manufacturing the cyclic olefin-based polymer in accordance with the present invention comprises heating a solution containing the cyclic olefin-based monomer to a temperature of 100 to 200°C and then adding a polymerization catalyst, to thereby perform the ring-opening polymerization.
