PROBLEM TO BE SOLVED: To provide a method for producing a norbornene-based resin molded product having excellent flame retardancy, reduced toxicity and environmental load, and having no odor problem with high productivity. SOLUTION: In a method for producing a norbornene-based resin molded body in which a norbornene-based monomer is bulk-polymerized in the presence of a flame retardant using a metathesis catalyst, at least two or more carbene carbons of the metathesis catalyst are bonded to ruthenium metal atoms. A production method is provided, wherein at least one of the carbene carbons is a ruthenium carbene complex having a group containing a hetero atom bonded thereto, and the flame retardant is a moisture releasing compound. |
