A styrene-based resin composition containing (A) a styrene-based resin having mainly syndiotactic configuration and (B) a rubber-like polymer, or further (C) an inorganic filler. The rubber-like polymer (B) includes, for example, (I) polymers produced by polymerizing vinyl monomers in the presence of polymers obtained through polymerization of one or more monomers selected from the group consisting of alkyl acrylate, alkyl methacrylate and polyfunctional monomers having conjugated diene-type double bonds, (II) block or graft copolymers selected from an a-b type block copolymer, an _-b-a type block copolymer, a b-a-b type block copolymer, an a grafted b copolymer and a b grafted a copolymer and (III) natural or synthetic rubber. The present composition is excellent in heat resistance and further in other physical properties such as impact resistance, stiffness and so on.
