To provide an antistatic resin composition capable of providing an molded article excellent in antistatic property, chemical resistance, surface smoothness of the molded article and impact resistance.

The antistatic resin composition is composed of (A) 7-91 mass% olefinic resin, (B) 2-60 mass% block copolymer containing an olefin polymer block and a hydrophilic polymer block, (C) 1.8-50 mass% block copolymer containing a polymer block of an aromatic vinyl compound and a polymer block of a conjugated diene compound or its hydrogenated product, (D) 5-50 mass% (rubber-reinforced) styrene-based resin having 0.2-1.2 dl/g intrinsic viscosity [] of acetone-soluble content and (E) 0.2-15 mass% methyl methacrylate-based (co)polymer having 1106 weight-average molecular weight or an aromatic vinyl compound-based (co)polymer having 1.5 dl/g intrinsic viscosity []. Component (B) may be a polymer (B2) containing 500 ppm of Na and K or a mixture of the polymer and a polymer (B1) containing 500 ppm of the contant.
