PROBLEM TO BE SOLVED: To provide a non-aqueous fine particle dispersion in which copolymer fine particles having an average particle diameter of 0.8-10μm and a narrow particle distribution are dispersed stably in a ketonic organic solvent. SOLUTION: The non-aqueous fine particle dispersion contains copolymer fine particles having an average particle diameter of 0.8-10μm and a standard deviation of at most 0.3μm. The copolymer is composed of: (1) 5-45 mass% of ethylenic unsaturated acid monomer units; (2) 0.1-50 mass% of poly-functional monomer units; and (3) 5-94.9 mass% of other copolymerizable monomer units.
