Abstract
A molded article produced by injection-molding a molten form of a flame-retardant aromatic polycarbonate resin composition comprising: 100 parts by weight of an aromatic polycarbonate (A) (Mw: 17,000 to 35,000), 0.01 to 3 parts by weight of inorganic compound particles (B) (average diameter: 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 FL/t ratio of the molded article is 50 or more, wherein FL is a flow length of the composition in a mold and t is a thickness of the molded article, the FL/t ratios being obtained by measuring the thicknesses of the molded article at portions corresponding to flow paths (L) (from a gate to points at which the flow of the composition stops) of the composition in the mold during the molding, and calculating an integral of (dL/T') along each (L) (dL: length of a segment of (L), t′: thickness of the molded article at a portion corresponding to the segment), wherein the calculated integrals are defined as the FL/t ratios.
