PROBLEM TO BE SOLVED: To provide a thermoplastic resin composition having excellent impact resistance and transparency.SOLUTION: The thermoplastic resin composition comprises 10 to 60 mass% of a graft copolymer (A) and 90 to 40 mass% of a thermoplastic resin (B) comprising a polymer containing vinyl cyanide monomer units. The (A) comprises a main chain consisting of a rubber-like polymer, and grafted chains, where the grafted chains comprise vinyl cyanide monomer units and monomer units of one or more kinds. In a component derived from the grafted chains, distribution of content of the vinyl cyanide monomer units has two or more peaks, namely a first peak having a peak top in a range of 0 to less than 10 mass% and a second peak having a peak top in a range of 10 to less than 55 mass%. A difference between representative values of the first peak and the second peak is 10 mass% or more. Further, a ratio "half-value width/peak height" of a loss modulus of the (A) is 0.1 to less than 0.25. |
