To provide a polycarbonate resin composition that has high chemical resistance and thermal aging resistance, barely shows a poor appearance during injection molding, and has excellent thermostability, and a molding including the resin composition.SOLUTION: A polycarbonate resin composition contains at least two polycarbonate resins that are different in the content of constitutional units derived from dihydroxy compounds represented by general formula (1). The polycarbonate resins each have a reduced viscosity that satisfies specific conditions.SELECTED DRAWING: None 【課題】高い耐薬品性及び耐熱老化性を有し、射出成形時の外観不良が少なく、かつ良好な耐熱性を有するポリカーボネート樹脂組成物および該樹脂組成物を使用した成形品を提供する。【解決手段】下記一般式（１）で表されるジヒドロキシ化合物に由来する構造単位の含有比率が異なる少なくとも２種のポリカーボネート樹脂を含み、それぞれのポリカーボネート樹脂の還元粘度が特定の条件を満たす、ポリカーボネート樹脂組成物。TIFF2022150358000010.tif2665【選択図】なし
