PROBLEM TO BE SOLVED: To provide a method for producing a water-dispersed resin emulsion, which method can disperse a fine resin emulsion of a median diameter of at most 1μm in water at a relatively low temperature at a good working efficiency without using any organic solvent and without using a large amount of an emulsifier. SOLUTION: The water-dispersed resin emulsion containing the resin emulsion having the median diameter of at most 1μm and dispersed in water is prepared by subjecting a resin to be emulsified to dry grinding with e.g. a jet mill, dispersing the resultant ground product in water, and subjecting the resultant dispersion together with an emulsifier to wet grinding with e.g. a medium-agitating mill desirably at 50°C or lower.
