To provide an antistatic resin composition which has excellent antistatic properties, chemical resistance, molded article surface appearance and thermal stability, and which has a reduced leaching amount of ions, and to provide a molded article.
An antistatic resin composition comprises 7-91 mass% of component (A), 2-60 mass% of component (B), 2-50 mass% of component (C), and 5-50 mass% of component (D) (provided that the sum total of components (A) to (D) is 100 mass%); component (A): an olefinic resin (excluding component (B)), component (B): a block copolymer comprising an olefin polymer block and a hydrophilic polymer block, component (C): a block copolymer comprising an aromatic vinyl compound polymer block and a conjugated diene compound polymer block or its hydrogenation product, component (D): a styrenic resin. A molded article of the antistatic resin composition has a surface resistivity (measured under conditions of 23°C and 50% RH) of ≤1×1011 Ω/sq. and has a leaching amount of sodium and potassium ions (measured under conditions of 80°C and extraction for 60 min) of ≤3 μg/cm2.
