Provided is a polycarbonate resin composition that is preferably used in an optical material, such as a lens, a film and a sheet, and has excellent environment resistance and low birefringence. The polycarbonate resin composition includes a polycarbonate resin (A) obtained by bonding a dihydroxy compound represented by general formula (1) through carbonate bonds by using a carbonic acid diester, and a polycarbonate resin (B) obtained by bonding 2,2-bis(4-hydroxyphenyl)propane through carbonate bonds by using a carbonic acid diester or phosgene. In the formula, R 1 and R 2 independently denote a hydrogen atom and a methyl group respectively. |
