PROBLEM TO BE SOLVED: To provide a resin molded product having excellent antistatic properties, independent of a process by which the product is molded, and having excellent mechanical strength. SOLUTION: An antistatic resin composition comprises a thermoplastic resin (A) and at least one kind of an antistatic agent (B) having such a refractive index that a difference between itself and that of the component (A) is not more than 0.02, wherein the antistatic agent (B) is selected from a group comprising (B1) a polyether ester amide which is derived from a polyamide having a number-average molecular weight of 200-5,000 and an adduct of an alkylene oxide to a bisphenol having a number-average molecular weight of 300-5,000 and (B2) a block polymer having such a structure that polyolefin blocks and hydrophilic polymer blocks having a volume specific resistance of 1×10<SP>5</SP>to 1×10<SP>11</SP>Ω×cm are repeatedly and alternately bonded to each other through at least one kind of bond selected from a group comprising an ester bond, an amide bond, an ether bond, an imide bond, and a urethane bond.
