PROBLEM TO BE SOLVED: To sort a sphericity of fine particles without contaminating qualified products with defective products even in the case where the fine particles are supplied at a high particle supply speed. SOLUTION: The sphericity sorter of fine particles drops fine particles 50 by applying vibration to a particle dropping plate in a transverse direction and separates qualified products 50A with good sphericity and defective products 50B with bad sphericity and the defective products 50B are dropped from a particle dropping plate 22 through a notch 46N formed in a middle of the particle dropping plate 22 and recovered under the particle dropping plate 22.
