PROBLEM TO BE SOLVED: To provide a resin composition suitable for a light reflector suitable for an LED emitter and excellent in heat resistance and light resistance, and to provide the light reflector.SOLUTION: A light reflector for LEDs is obtained by employing a resin composition including: a crystalline cyclic olefin ring-opened polymer hydrogenation product having a repeating unit derived from a polycyclic norbornene monomer; a titanium oxide of 20-100 pts.wt. with respect to the hydrogenation product of 100 pts.wt.; and a light stabilizer of 1/500 to 1/150 times weight with respect to a weight of the titanium oxide, having a N-substituted piperidine structure. |
