PROBLEM TO BE SOLVED: To provide a method for producing a cellulose microfiber having a nano-size， high crystallinity and little damage of a fiber shape by an energy-saving process which does not require strong physical grinding， and to provide a method for producing a modified cellulose microfiber. SOLUTION: A method for producing cellulose microfiber comprises allowing a defibration solution containing a carboxylic acid vinyl ester or aldehyde and an aprotic solvent having 26 or more donors to permeate cellulose to defibrate the cellulose. The aldehyde is at least one aldehyde selected from the group consisting of aldehyde represented by formula (1)， paraformaldehyde， cinnamaldehyde， perillaldehyde， vanillin and glyoxal: R 1-CHO (1) (In the formula， R1 represents a hydrogen atom， an alkyl group having 1 to 16 carbon atoms， an alkenyl group， a cycloalkyl group or an aryl group).SELECTED DRAWING: Figure 1
