Disclosed is a polycarbonate resin composition containing aluminum oxide nanoparticles that has good moldability and residence heat stability, and has high transparency, dimensional stability, and excellent mechanical properties. According to JISK7210 method, the melt mass flow rate measured under the conditions of a temperature of 280 ° C., a nominal load of 2.16 kg and a nozzle size L / D = 8/2 is 11 g / 10 min. No. 2 dumbbell-shaped test piece described in JIS K7113 of a 0.2 mm-thick film obtained by hot press molding was measured under the conditions of a temperature of 23 ° C., a humidity of 50% RH, and a tensile speed of 50 mm / min. A polycarbonate resin composition having a fracture stress of 8 MPa or more. As the organic acid, an organic sulfonic acid having 8 or more carbon atoms is preferable, and an organic sulfonic acid having an aromatic ring in the molecule is particularly preferable.
