Abstract
A resin composition containing a polycarbonate resin and a fluorine-containing copolymer. The fluorine-containing copolymer is a copolymer containing a polymerized unit based on tetrafluoroethylene in an amount of 75% by mass or more of all polymerized units and at least one selected from a polymerized unit based on hexafluoropropylene and a polymerized unit based on a perfluoro(alkyl vinyl ether) in an amount of 2% by mass or more. Also disclosed is a molded article formed from the resin composition, the polycarbonate resin constituting a continuous phase and the fluorine-containing copolymer constituting a dispersed phase having an average particle size of 0.01 to 2.5 μm.
