PROBLEM TO BE SOLVED: To provide a thermoplastic resin composition having a feature that a stress is smaller and a deformation amount is larger as a deformation speed is higher, and has a good balance of conflicting properties such as impact resistance and heat resistance, and particularly excellent in impact resistance. In particular, a highly structurally controlled thermoplastic resin composition having specific tensile properties is provided. A thermoplastic resin composition comprising a thermoplastic resin (A) and a resin (B) having a reactive functional group, and having the following characteristics (I) and (II). (I) Assuming that the tensile elastic modulus at the tensile speeds V1 and V2 after the tensile yield elongation in the tensile test is E (V1) and E (V2), E (V1)> E ( V2) (II) If the stress at the time of V1, V2 in the tensile elongation ε after the tensile yield elongation in the tensile test is σ (V1, ε), σ (V2, ε), when V1 <V2, σ (V1, ε)> σ (V2, ε) [Selection figure] None |
