The present invention pertains to a method for producing a fine fiber, the method encompassing a step for treating raw cellulose with an enzyme, and a step for separating the treated raw cellulose; the step for treatment with an enzyme comprising a step for treatment under conditions where at least the ratio between EG activity and CBHI activity is 0.06 or greater. Preferably, the raw cellulose is chosen from a plant fiber. According to the present invention, it is possible to provide: a method for producing a fine fiber, with which a fine fiber is produced efficiently from raw cellulose, costs are low, and the environmental burden is small; a fine fiber; and a non-woven fabric. |
