PROBLEM TO BE SOLVED: To provide a method for producing a cellulose nanofiber dispersion liquid, in which dispersibility of a cellulose nanofiber in a dispersion medium can be improved and the energy required to re-disperse the cellulose nanofiber in the dispersion medium can be saved.SOLUTION: The method for producing the cellulose nanofiber dispersion liquid comprises: a cellulose nanofiber production step (1) of producing the cellulose nanofiber from a carboxyl group-containing cellulose fiber to be obtained by oxidizing a natural cellulose fiber by using an oxidizer and an N-oxyl compound; a step (2) of mixing the produced cellulose nanofiber with a re-dispersion accelerator to obtain a gelatinized body; and a step (3B) of mixing the obtained gelatinized body, an organic liquid compound, and a dispersant to re-disperse the cellulose nanofiber. |
