An object of the present invention is to provide fine particles excellent in biodegradability and touch feeling. Disclosed are cellulose acetate particles, the cellulose acetate particles have an average particle size of 80 nm or more and 100 μm or less, a sphericity of 0.7 or more and 1.0 or less, and a surface smoothness of 80% or more and 100% or less, and the cellulose acetate has a total degree of acetyl substitution of 0.7 or more and 2.9 or less.
