<p>This resin composition contains an acrylic-based resin and a polycarbonate-based resin at a ratio of 50 to 95 mass% and 5 to 50 mass%, respectively. The acrylic-based resin comprises a copolymer obtained by polymerizing monomer components comprising 50 to 95 mass% methyl methacrylate, 5 to 50 mass% ester (meth)acrylate represented by formula (I), and 0.1 to 20 mass% other monofunctional monomer, and has a viscosity-average molecular weight of 80000 to 300000. The polycarbonate-based resin has a viscosity-average molecular weight of 16000 to 25000. The ratio (etaA/etaB) between the melt viscosity (etaA) of the acrylic-based resin at a temperature of 240°C and a shear rate of 60sec-1 and the melt viscosity (etaB) of the polycarbonate-based resin at a temperature of 240°C and a shear rate of 60sec-1 is 0.40 to 3.00, and formula (a) is satisfied.</p> |
