PROBLEM TO BE SOLVED: To provide a production method of an aqueous dispersion of resin, in which a generation amount of waste is reduced. SOLUTION: The production system of the aqueous dispersion of resin comprises: a dispersion tank housing the resin aqueous dispersion containing a resin, water and an organic solvent; a recovering means recovering at least a part of the water and the organic solvent from the resin aqueous dispersion; a conductivity measuring means measuring the conductivity of a recovered liquid containing at least one of the recovered water and organic solvent; a classifying means classifying the recovered liquid; a weight measuring means measuring the weight of a classified liquid; a control means controlling the classifying means in accordance with the measured conductivity and weight; and a supplying means supplying the classified liquid consisting essentially of water of the classified liquids, as an addition water for the production of the resin aqueous dispersion.
