PROBLEM TO BE SOLVED: To provide a method for producing a norbornene resin molded article having good flame retardancy, lowered toxicity, environmental load and no odor, with a good productivity. SOLUTION: The method for producing a norbornene resin molded article by bulk polymerization of a norbornene monomer uses a methathesis catalyst in the presence of a flame retardant. The methathesis catalyst is as a ruthenium/ carbene complex in which at least two carbene-carbon atoms are bonded to the ruthenium metal atom and at least one of the carbene-carbon atom bonds a group having a hetero atom. A water-releasing compound is used as a flame retardant.
