    摘要: A light reflector which can be manufactured easily by using a plastic base material that is light weight and low cost and has high reflectivity, and a method for manufacturing the same. The light reflector comprises a plastic base material 50 of which thermal deformation temperature is 130° C. or higher, and a reflecting film 52 containing silver and formed on the surface of the base material, wherein said plastic base material 50 is a molded article of thermosetting resin and the reflecting film has a smooth surface with PV (peak-to-valley) roughness of 0.5 μm or less without sharp protrusions and reflectivity of the reflecting film is 96% or more.
