Provided is a thermoplastic resin composition exhibiting both high transmittance and low haze and having excellent transparency and excellent scratch resistance and toughness. The thermoplastic resin composition of the present disclosure contains 50% to 99% by mass of methacrylic resin (A) and 1% to 50% by mass of thermoplastic polyurethane (B), wherein the methacrylic resin (A) contains 80.0% to 99.9% by mass of methacrylate ester monomer unit, 0.1% to 20.0% by mass of vinyl monomer unit containing a vinyl monomer copolymerizable with a methacrylate ester monomer excluding maleic acid and maleic anhydride, and 0% to 4.0% by mass of maleic acid and/or maleic anhydride monomer unit, and the thermoplastic polyurethane (B) has a structural unit derived from polyester polyol and a structural unit derived from isocyanate having an alicyclic ring.
