PROBLEM TO BE SOLVED: To provide a method for producing an aqueous resin solution whereby a residual monomer is effectively removed from the solution and hence the resultant aqueous resin solution has a low residual monomer content. SOLUTION: An aqueous resin solution containing a residual monomer is brought into contact with a substance having an ion-exchange function to remove electrolytic impurities from the solution. Then, cyclodextrin is added to the solution, and an inclusion compound of cyclodextrin and the residual monomer in the solution is formed at a pH of 6.0 to 9.0. The inclusion compound is removed by centrifugal separation at a rotation speed of 10,000 rpm. Thus, an aqueous resin solution reduced in the residual monomer content is produced.
