The present invention provides a method for producing fine fibrous cellulose that is excellent in dispersibility in a resin, has a high yield of fine fibrous cellulose in the defibrating process, and has a low cost for production. The method for producing fine fibrous cellulose of the present invention comprises a suspension preparation step for obtaining a cellulose suspension containing at least one of unbleached chemical pulp and oxygen bleached chemical pulp, (A) to (e) having a chemical treatment step for performing at least one chemical treatment, and a defibration step for subjecting the cellulose suspension after the chemical treatment step to a defibration treatment. And (A) treatment of a compound having a carboxy group with an acid anhydride, (b) treatment with a compound having a phosphate group, (c) treatment with ozone, (d) treatment with an enzyme, (e) 2, 2, 6, Treatment with 6-tetramethylpiperidinooxy radical [selection] None |
