Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for producing a cellulose derivative, capable of converting celluloses into cellulose derivatives having various substituents and substitution degrees in a short time in a small amount of by-products at a low process cost. SOLUTION: This method comprises carrying out a reaction process (b) in an electromagnetic field having 10 MHz to 23 GHz frequency in a method for producing a cellulose derivative by (a) activating the cellulose and (b) reacting the activated cellulose with one or more kinds of reagents, if required, in the presence of a suspending agent.
