PROBLEM TO BE SOLVED: To provide a thermoplastic resin composition having excellent stability, low temperature impact resistance and flowability, and to provide a molded article. SOLUTION: This thermoplastic resin composition comprising an aromatic polycarbonate (A), a graft polymer (B), and a vinylic copolymer (C) comprising aromatic vinylic monomer units and vinyl cyanide-based monomer units is characterized in that the graft polymer (B) is obtained by graft-polymerizing a monomer mixture (b-2) comprising 65 to 90 mass% of an aromatic vinylic monomer and 10 to 35 mass% of a vinyl cyanide-based monomer to a latex-like rubbery polymer (b-1) comprising an ethylene-propylene-non-conjugated diene copolymer and a modified low mol.wt.α-olefin copolymer, wherein the rate of rubber particles having mass-average particle diameters of 250 to 400 nm and particle diameters of≥500 nm is <25%.
