The present invention provides a resin composition that is excellent in terms of impact resistance, flowability, heat resistance, and chemical resistance and gives molded articles which have a satisfactory appearance and are highly inhibited from making a noise when rubbed against each other. This resin composition is characterized by comprising: 100 parts by weight of a component comprising (A) 45-90 parts by weight of a polycarbonate resin (A component) and (B) 10-55 parts by weight of a copolymer (B component) obtained by polymerizing an aromatic vinyl monomer, a vinyl cyanide monomer, and a diene-based rubbery polymer, (C) 1-10 parts by weight of a graft copolymer (C component) comprising a copolymer obtained by polymerizing an aromatic vinyl monomer and other vinyl monomer(s), as side chains, and an ethylene/vinyl acetate copolymer as a main chain, and (D) 1-10 parts by weight of an isobutylene based block copolymer (D component) obtained by polymerizing one or more monomers including isobutylene as a main component with one or more monomers in which isobutylene is not a main component.
