A thermoplastic resin composition containing a graft copolymer (A) and a thermoplastic resin (B), in which the thermoplastic resin (B) contains a polymer having a vinyl cyanide monomer unit, the graft copolymer (A) and the thermoplastic resin (B) are contained in predetermined proportions based on the total amount of the graft copolymer (A) and the thermoplastic resin (B), the graft copolymer (A) has a main-chain polymer formed of a rubbery polymer and a graft chain, the graft chain has a vinyl cyanide monomer unit and at least one monomer unit copolymerizable with the vinyl cyanide monomer, the distribution of the content of the vinyl cyanide monomer unit in components derived from a graft chain has peak 1 having a peak top within a content range from 0 mass% or more to less than 10 mass%, and peak 2 having a peak top within a content range from 10 mass% or more to less than 55 mass%, and the difference between a representative value of the content represented by peak 1 and a representative value of the content represented by peak 2 is 10 mass% or more. |
