PROBLEM TO BE SOLVED: To provide a method for obtaining a composite of fine cellulose fiber and a resin without preliminarily producing nonwoven fabric or the like of cellulose fiber before producing the composite.SOLUTION: A method for producing a dispersion of fine cellulose fiber is provided, wherein the fine cellulose fiber is obtained by defibrating cellulose fiber in a dispersion containing the cellulose fiber and an organic solvent with a viscosity of at least 1.0 and a refractive index of at least 1.40. The dispersion of fine cellulose fiber is produced by the production method. A fine cellulose fiber-resin dispersion contains the dispersion of fine cellulose fiber and a resin and/or a resin precursor. A cellulose fiber composite is produced by using the fine cellulose fiber-resin dispersion, and a method for producing the cellulose fiber composite is provided. |
