[PROBLEMS] To provide a thermoplastic resin composition containing a methacrylic resin (A) and a polyvinyl acetal resin (B), which is further excellent in transparency and hue, with few defects such as fish eyes, and excellent in surface smoothness. Provided is a thermoplastic resin composition capable of stably producing products and films with good reproducibility. SOLUTION: A methacrylic resin (A), a polyvinyl acetal resin (B) obtained by acetalizing a polyvinyl alcohol resin with an aldehyde having 4 or less carbon atoms at an acetalization degree of 65 to 85 mol%, and a methacrylic resin. 1 ppm or more and 200 ppm or less of acetaldehyde (E1) with respect to the total of (A) and polyvinyl acetal resin (B), and 1 ppm or more and 200 ppm or less of butyl with respect to the total of methacrylic resin (A) and polyvinyl acetal resin (B) An acrylic thermoplastic resin composition containing aldehyde (E2).
