To provide a polycarbonate resin composition excellent in thermal stability in heat molding, and excellent in the color hue after molding.

The polycarbonate resin composition contains at least a polycarbonate resin having a structural unit originated from a dihydroxy compound having a site represented by formula (1) as a part of the structure, and contains 0.001 to 0.5 pts.mass of a compound represented by formula (2) based on 100 pts.mass of the polycarbonate resin. Here, the case where the site represented by formula (1) is a part of -CH₂-O-H is excluded. In the formula (2), Ar¹, Ar² and Ar³ are each independently a 6-20C aryl group, and may have a 1-10C alkyl group as a substituent.
