A molded article is produced from a flame retardant resin composition obtained by compounding a thermoplastic resin or thermosetting resin with a flame retardant composition comprising as essential ingredients a fluorine compound (A) represented by the following formula (1): R1—SO2—R2 or R1—SO3−M+  (1) (wherein R1 represents a C1-C12 perfluoroalkyl group, a C2-C8 perfluoroalkenyl group, a C6-C12 perfluoroaryl group which may be substituted, a C3-C12 perfluoroalicyclic hydrocarbon group, or a C7-C12 perfluoroaralkyl group; R2 represents a halogen atom, an N-alkylamino group, or an N-alkyl-N-hydroxyalkylamino group; and M represents an alkali metal) and a polyester resin (B). The molded article has flame retardancy despite addition of the fluorine compound (A) in a very small amount. Excellent dispersion of the fluorine compound (A) is attained, and bleeding of the compound (A) is prevented.
