PURPOSE: Provided is a process for producing a cyclic olefin polymer containing a polar functional group in a high yield and a high molecular weight, which has low dielectric constant, low hygroscopicity, high glass transition temperature and is excellent in heat stability, oxidative stability, and chemical stability. CONSTITUTION: The cyclic olefin polymer contains the polar functional group having a molecular weight of at least 100,000 and is produced by addition-polymerizing a monomer containing a norbornene monomer containing the polar functional group in the presence of a catalyst system at 80-130deg.C, wherein the catalyst system contains a 10 group transition metal compound as a catalyst represented by the formula 1 or 2, an organic compound containing a 15 group element as a first cocatalyst, and a salt giving an anion containing a 13 group element as a second cocatalyst. In the formula, M is the 10 group metal, n is 1 or 2, R1 and R2 are independently hydrogen, C1-C20 linear or branched alkyl, alkenyl, or vinyl, hydrocarbon substituted or unsubstituted C5-C12 cycloalkyl, hydrocarbon substituted or unsubstituted C6-C40 aryl, C6-C40 aryl containing a hetero element, and etc, and R3 is hydrogen, halogen, C1-C20 linear or branched alkyl, allyl, alkenyl, or vinyl, hydrocarbon substituted or unsubstituted C5-C12 cycloalkyl, and etc.
