PROBLEM TO BE SOLVED: To provide a vibration-damping thermoplastic resin composition exhibiting high vibration-damping performances in a wide frequency region in a practical temperature region and excellent in the balance among impact resistance, mechanical strength, rigidity, heat resistance and other properties and in chemical resistance, and a thermoplastic resin molded article obtained by molding the thermoplastic resin composition. SOLUTION: The vibration-damping thermoplastic resin composition comprises (A) a polyamide resin, (B) a graft copolymer obtained by polymerizing at least an aromatic vinyl monomer and a vinyl cyanide monomer in the presence of a conjugated diene-based rubbery polymer, (C) a graft copolymer obtained by polymerizing an aromatic vinyl monomer and a vinyl cyanide monomer in the presence of a rubbery polymer comprising an ethylene/propylene/nonconjugated diene copolymer having incorporated therewith an acid-modified low-molecular weightα-olefin copolymer, and (D) a copolymer obtained by polymerizing at least an aromatic vinyl monomer and a vinyl cyanide monomer.
