PROBLEM TO BE SOLVED: To obtain the subject composition specified in the size distribution range of included particles, and capable of giving a molded product having high impact resistance, excellent in surface luster and quality balance. SOLUTION: This composition comprises (A) a styrene-based polymer as continuous phase and (B) rubbery polymer particles dispersed as disperse phase, having the following characteristics: the weight-average particle diameter of the component B is 0.3-2.0 (esp. 0.3-1.5)μm: the component A is included in the form of particles in the component B; the proportion of the rubbery polymer particles each including three or more particles of the component A accounts for >=70% of the component B; and >=50% of the number of the included particles (A) are those having a diameter of >0.3μm.
