A cellulose resin composition comprising a cellulose resin, a high refractive-index organic material and a carbon black, in which the cellulose resin is an acylated cellulose obtained by substituting at least part of hydrogen atoms of hydroxy groups of a cellulose with an acyl group having 2 to 4 carbon atoms, the carbon black is an acidic carbon black, the mass fraction (B/A) of the high refractive-index organic material (B) to the cellulose resin (A) falls within the range of 10/90 to 70/30, and the content of the carbon black (C) relative to the total of the cellulose resin composition falls within the range of 0.05 to 10% by mass.
