<P>PROBLEM TO BE SOLVED: To provide a molded product for an optical member which is formed by using a cyclic olefinic resin composition, and has excellent durability and heat stability to short-wavelength light of about 405 nm. <P>SOLUTION: The molded product is formed by using the cyclic olefinic resin composition including 100 pts.wt. of a cyclic olefinic resin having a structural unit derived from a monomer represented by formula (1), and 0.05-3 pts.wt. of at least one sulfur-based stabilizer selected from the group consisting of the sulfur-based stabilizers represented by formulas (2) to (5): R-S-H (2); R-S-R (3); R-S-S-R (4); and -(-R-S-R) (5). The molded product is used for the optical member using light at 395-420 nm wavelength. <P>COPYRIGHT: (C)2010,JPO&INPIT |
