Abstract: Provided are: a light-reflecting component which has excellent continuous moldability, heat resistance and surface properties (low diffuse reflectance); and a method for producing the light-reflecting component. A method for producing a light-reflecting component, the method comprising a step of injection-molding a resin composition obtained by melting and kneading a mixture containing 100 parts by mass of (A) a polyarylene sulfide resin, 10 to 120 parts by mass of (B1) a fibrous inorganic filler having a fiber length of 1 to 5 mm and 10 to 220 parts by mass of (C) a particulate filler using a mold in which a cavity surface is subjected to a surface treatment to be coated by a diamond-like carbon coating film.
