A thermoplastic resin molded product comprises a thermoplastic resin containing 5 to 40% by weight of rubber particles. The rubber particles present near the surface of the molded product fulfill conditions of the equations (1) to (4): (b/a) 2 (1) where a and b are the average minor and major axis lengths in a section of the rubber particles, 1 {(b/a)max.}/{(b/a)min.} 1.5 (2) where {(b/a)max.} and {(b/a)min.} are the maximum and minimum values of the ratios of (b/a), and 0 (Amax.-A)/A 0.2 (3) 0 (A-Amin.)/A 0.2 (4) where Amax. and Amin. are the maximum and minimum values of the proportions of the areas accounted for by the rubber particles in sections of the molded product, and A is the average value of the proportions.
