The invention relates to a catalyst for the polymerization of norbornene monomers comprising transition metal complex (A) represented by formula (1); and a method for producing a norbornene (co)polymer, especially a norbornene copolymer containing a monomer unit represented by formulae (2) and (3), wherein a norbornen monomer is homopolyzed or copolymerized in the presence of the polymerization catalyst. Preferable examples of the transition metal complex (A) include (π-allyl)4-(2,6-diisopropylphenylimino)-2-penten-2-olato-κ2N,O}palladium and (π-allyl)4-(1-naphthylimino)-2-penten-2-olato-κ2N,O}palladium. In the formulae, the symbols are as defined in the description. A norbornene (co)polymer which has excellent transparency, excellent heat resistance, excellently low water absorption and excellent electrical insulation characteristics can be efficiently produced by the present invention.
