<p>Disclosed is a light reflector containing a heat-resistant silver alloy light-reflecting material, which has optical characteristics comparable to light reflectors using Ag films and is suppressed in deterioration of the optical characteristics even after being subjected to a heat treatment that is necessary for forming anatase TiO2 which is a typical photocatalyst material. Specifically disclosed is a light reflector for infrared light or the like, which is characterized by comprising a light-reflecting layer that contains a heat-resistant Ag alloy light-reflecting material containing 1-7 wt% of Sb with the balance made up of Ag and unavoidable impurities and an additional layer that is mainly composed of a metal oxide selected from among ITO, SiO2, SnO2, Ta2O5, Nb2O5 and Al2O3.</p> |
