PROBLEM TO BE SOLVED: To provide a method for preparing a mixed solution and a method for producing an absorber, which are excellent in dispersibility of a cellulose derivative and a non-fibrous water-soluble polymer, and can obtain a mixed solution in which the formation of lumps in a solvent is suppressed. thing. A method for preparing a mixed solution of the present invention is a method for preparing a mixed solution containing a cellulose derivative and a non-fibrous water-soluble polymer. The method for preparing the mixed solution includes a pre-dispersion step of dispersing a powdered cellulose derivative and a powdered non-fibrous water-soluble polymer in a polyhydric alcohol-based dispersion medium to obtain a pre-dispersed liquid, and a pre-dispersed liquid. Is mixed with at least one of the main solvent of water and an alcoholic solvent to prepare a mixed solution. In the method for producing an absorbent body of the present invention, the absorbent body of the absorbent article is produced using the mixed solution prepared by the method for preparing the mixed solution.
