Abstract: Disclosed herein is an interior/exterior automotive trim component in which each of carbonate copolymers forming a polycarbonate resin composition is comprised of structural units derived from two or more different dihydroxy compounds. The structural units derived from the dihydroxy compounds include an ISB unit and a CHDM unit. In every one of the plurality of carbonate copolymers that form the polycarbonate resin composition, a molar ratio of the ISB unit to every dihydroxy compound unit in the carbonate copolymer is equal to or greater than 30 mol %. The molar ratio of the ISB unit to the CHDM unit in the polycarbonate resin composition satisfies 53/47≦ISB unit/CHDM unit≦56/44.
