Abstract:
1. A molded article of a flame-retardant aromatic polycarbonate resin composition, which is produced by injection-molding a molten form of a flame-retardant aromatic polycarbonate resin composition in a mold having at least one gate for introduction of said resin composition, said flame-retardant aromatic polycarbonate resin composition comprising: 100 parts by weight of an aromatic polycarbonate (A) having a weight average molecular weight of from 17,000 to 35,000, 0.01 to 3 parts by weight of inorganic compound particles (B) having an average particle diameter of from 10 nm to 10 μm, 0.001 to 0.5 part by weight of an alkali metal salt (C) of an organic sulfonic acid, and 0.01 to 0.5 part by weight of a fluoropolymer (D) wherein the largest value of FL/t ratios of the molded article is 50 or more, wherein FL represents a flow length of said resin composition in the mold and t represents a thickness of said molded article, said FL/t ratios being obtained by a method comprising: measuring the thicknesses of the molded article at portions thereof which, respectively, correspond to flow paths (L) of said molten form of the resin composition in said mold during the injection molding, said flow paths (L) extending from said gate of the mold to points in the mold at which the flow of said molten form of the resin composition stops, and calculating an integral of (dL/t′) along each of said flow paths (L), wherein dL represents the length of a segment of flow path (L) and t′ represents the thickness of the molded article at a portion thereof which corresponds to said segment, wherein the integrals respectively calculated with respect to said flow paths (L) are defined as the FL/t ratios of the molded article.
