Polyamide composition, and molded article including same

A polyamide composition comprising

• a polyamide (A) having a melting point of 280° C. or higher and
• a flame retardant (B),
• which is such that, when a melt of the polyamide composition is injection-molded with a mold having a thickness of 0.5 mm and a width of 40 mm under the condition of a cylinder temperature higher by 20° C. than the melting point of the polyamide (A), an injection pressure of 74 MPa and a mold temperature of 140° C., the flow length is 40 mm or more, and
• that the melt flow rate of the polyamide composition at a temperature of 320° C. and under a load of 2.16 kg is 15 g/10 min or less;
• wherein the polyamide composition further comprises an aromatic vinyl copolymer (C),
• wherein the aromatic vinyl copolymer (C) contains
• a structural unit derived from an aromatic vinyl monomer, and
• a structural unit derived from an α,β-unsaturated dicarboxylic anhydride;
• and
• wherein the content of the α,β-unsaturated dicarboxylic anhydride-derived structural unit in the aromatic vinyl copolymer (C) is from 18 to 28% by mass.
