Abstract: Provided are: a cellulose fiber manufacturing method for suppressing the occurrence of thread breakage in a spinning step and unevenness in the physical properties of obtained fibers, thus enabling stable spinning; and cellulose fibers that are highly strengthened, in which fibrillation is suppressed, and that have a pleasant texture. The present invention provides a cellulose fiber manufacturing method including the following steps: a solution preparation step for dissolving cellulose in a mixed solvent of an aprotic polar solvent and a quaternary onium salt; a discharge step for discharging the obtained solution in a fibrous form through a spinneret, the moisture content of the solution at the time of discharging falling within the range from 0.05 mass % to 8 mass %; and a solidification step for solidifying the discharged fibers in a water-based solidification bath containing water and the mixed solvent.
