Disclosed is a rubber-reinforced resin which, when formed into a molded article, can prevent the contamination or soiling of an article contacted with the molded article or a device on the periphery of the molded article, and is excellent in impact resistance and transparency. Also disclosed is an anti-static resin composition which is excellent in impact resistance and anti-static property. The rubber-reinforced resin comprises a rubber-reinforced copolymer resin produced by polymerizing 20 to 95 parts by mass of monomer components comprising methyl methacrylate, an aromatic vinyl compound and a vinyl cyanide compound in the presence of a rubbery polymer having a predetermined volume average particle diameter, or comprises a mixture of the rubber-reinforced copolymer resin and a copolymer of the above-mentioned monomer components. The anti-static resin composition comprises the rubber-reinforced resin and a polymeric anti-static agent, wherein the rubbery polymer is contained in an amount of 5 to 40% by mass. In each of the rubber-reinforced resin and the anti-static resin composition, the total amount of the substances detected at a retention time of 10 to 24 minutes is 20,000 μg or less per gram of the sample as determined by pyrolysis GC analysis.
