To provide an antistatic resin composition for injection molding which prossesses excellent washing resistance without sacrificing surface appearance and exhibits a permanent antistatic property.

An antistatic resin molding is obtained by mixing a thermoplastic resin (A) with a hydrophilic resin (B) and a resin (C) compatible or semi-compatible with the resin (B). In this case the weight mixing ratios a, b and c of the resins (A), (B) and (C) meet 0.9≤a≤0.99, 0.01≤b+c≤0.1 and 0.0005b≤c≤0.1b. The resin (B) taking in the resin (C) is uniformly dispersed as particles in the matrix of the resin (A), the weight average diameter of the dispersed particles being 0.1×10-6m4.0×10-6m and an average relaxation time of molecular chains during injection molding being 1×101-8.0×104 seconds.
