A flame-retardant styrene-based resin composition which comprises: (a) 100 parts by weight of a blend of a styrene- based resin and a rubber-modified styrene-based resin, or a rubber-modified styrene-based resin; (b) from 1 to 45 parts by weight of a bromine compound having a bromine content of 40 wt% or more and a melting point of 80°C or higher; (c) from 0.5 to 15 parts by weight of antimony trioxide; and (d) from 1 to 30 parts by weight of glass fibers, wherein the heat distortion temperature of a molded product obtainable from said composition is 85°C or higher and the impact strength thereof is 5.0 kg?cm/cm or more, is disclosed. The flame-retardant styrene-based resin composi- tion of this invention is excellent in flame retardance, heat resistance, and impact resistance without injuring the inherent mechanical characteristics of the styrene- based resin. Further, any of the components which are incorporated in the flame-retardant styrene-based resin composition of this invention are not only easy to handle but also nonpoisonous, so that the molded products obtained from the composition are useful as armoring materials, or the like, of light electric appliances, office machines, etc.
