<p>PROBLEM TO BE SOLVED: To provide a polycarbonate resin composition which has high flowability and heat resistance, hardly causes appearance failures such as flow marks or tiger marks on a molding during injection molding, and has good impact resistance, and to provide a molded article using the resin composition.SOLUTION: A polycarbonate resin composition is obtained by melt mixing a plurality of carbonate copolymers having different copolymerization ratios. The plurality of carbonate copolymers are each constituted of a structural unit derived from two or more kinds of dihydroxy compounds and have at least a structural unit derived from a dihydroxy compound having an ether structure in the molecule. The melt viscosity of a carbonate copolymer having the lowest copolymerization ratio of the structural unit derived from the dihydroxy compound having an ether structure in the molecule is equal to or less than the melt viscosity of a carbonate copolymer having the highest copolymerization ratio of the structural unit derived from the dihydroxy compound having an ether structure in the molecule.</p> |
