Disclosed is a reflective material having high reflectance to ultraviolet light, which maintains high reflectance even after a heat treatment. Also disclosed is a reflector for LEDs. Specifically disclosed is a reflective material which is composed of a polymer obtained from a composition containing the following components (a) and (b). (a) 95-30% by mass of a thermally polymerizable or photopolymerizable compound (b) 5-70% by mass of hollow particles which are made of a material having an ultraviolet light transmittance at a wavelength of 350 nm of 50% or more. |
