Abstract: Provided are: a flame retardant agent composition which has excellent flame retardancy as well as an excellent balance of dust suppression and powder flowability; a flame-retardant resin composition containing the same; and a molded article thereof. The flame retardant agent composition contains at least one phosphate compound represented by Formula (1) or (2). When the loose bulk density of the flame retardant agent composition is defined as d (g/cm3), and the 10% cumulative particle size and the 50% cumulative particle size of the flame retardant agent composition in a volume-based particle size distribution are defined as D10 (μm) and D50 (μm), respectively, d, D10 (μm), and D50 (μm) satisfy 0.030≤d/(D50−D10)≤0.110.
