PROBLEM TO BE SOLVED: To provide a resin molded item exhibiting excellent dimensional stability, a manufacturing method of the resin molded item that causes no nozzle clogging in a molding apparatus on molding, and a reaction stock solution that exhibits excellent preservation stability and is suitably employable for the manufacturing method. SOLUTION: The norbornene resin molded item is obtained by bulk polymerization of norbornene monomers in a mold and contains aluminum hydroxide having an aspect ratio of 5-100. Preferably, the average major axis diameter of aluminum hydroxide is 5-500μm. Especially preferably, the molded item comprises 100 pts.wt. of norbornene monomers and, incorporated therewith, 5-400 pts.wt. of aluminum hydroxide. COPYRIGHT: (C)2007,JPO&INPIT |
