ABSTRACT A molded article of a norbornene polymer is produced by mixing a starting reaction liquid (liquid A) containing an activator of a methathesis catalyst system with a starting reaction liquid (liquid B) containing a catalyst component of the methathesis catalyst system and supplying the mixture into a mold, wherein a norbornene monomer is incorporated in at least one of the starting reaction liquids and a liquid product obtained by ring-opening bulk poly- merization of a norbornene monomer is used as the viscosity modifier for the starting reaction liquids; the molded article has increased mechanical strength and good finish, problems associated with the low viscosity of norbornene monomer, insufficient curing and formation of voids are avoided.
