Claim:
1. A light reflector, comprising: a light reflecting metal layer; and a molded article having a surface; wherein the light reflecting metal layer is directly formed on at least a part of the surface of the molded article, and the molded article comprises: a thermoplastic resin (A) at least one of an ester of a fatty acid and a salt of fatty acid in an amount of from 0.01 to 3 parts by mass with respect to 100 parts by mass of the thermoplastic resin (A); and 2 to 45 parts by mass of precipitated barium sulfate per 100 parts by mass of the thermoplastic resin (A); wherein the thermoplastic resin (A) contains a polyester resin (a), the polyester resin (a) contains a polybutylene terephthalate (a-1) and a polyethylene terephthalate (a-2), an amount of the polyester (a) is 85% by mass or more with respect to a total mass of the thermoplastic resin (A), a refractive index (α) of the precipitated barium sulfate is from 1.64 to 1.65, an average particle diameter of the precipitated barium sulfate is 3 μm or less, and a diffused reflectance of the light reflector after a heat resistance test is not more than 3%.
