A method is provided for producing particles which is capable of producing particles in simple and easy steps. The objective is to provide with a high yield particles having a homogeneous particle diameter and a superior dispersibility in liquid. The method includes (1) preparing an aqueous solution containing one or more polymer; and (2) introducing the aqueous solution as droplets into a solvent capable of dissolving water by 1 mass % or more and less than 50 mass % to form the polymer into dispersed particles in the mixture of the aqueous solution and the solvent in the mixture of the aqueous solution and the solvent.
