An object of the present invention is to provide a production method capable of easily producing an aqueous dispersion of polyolefin having a fine dispersed particle size and a narrow particle size distribution, and capable of greatly simplifying the production process. A method for producing an aqueous resin dispersion comprising a modified polyolefin and water, wherein the modified polyolefin is dissolved in a solvent (a1) having a water solubility of less than 1.0% by weight at 20 ° C. On the other hand, a dispersion step in which a solvent (a2) having a water solubility at 20 ° C. of 1.0% by weight or more and water are added and dispersed, and at least the solvent (a1) and the solvent (a2) are distilled off. A method for producing an aqueous resin dispersion, comprising a step. [Selection figure] None |
