【Task】 An object of the present invention is to provide a method for producing a cellulose nanofiber dispersion capable of suppressing a decrease in viscosity over time, generation of a strange odor, appearance deterioration, and achieving improvement in productivity. [Solution] Cellulose nano having a fibrillation treatment process for treating anion-modified cellulose in the presence of a dispersion medium and a sterilization process for treating the anion-modified cellulose that has been defibrated and dispersed at a heating rate of 1.0 × 10 5 ° C / second or more. A method for producing a fiber dispersion. [Selection figure] None |
