Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method of manufacturing natural fiber moldings, capable of efficiently manufacturing the moldings by suppressing manifestation of adhesiveness due to contact between compatible polymer and biodegradable resin. SOLUTION: This is the method of manufacturing natural fiber moldings containing natural fiber (kenaf fiber) and biodegradable resin (polylactic acid) having thermoplasticity. The method includes, in this order: a sticking process in which the biodegradable resin stuck with the compatible polymer is obtained by bringing a sticker 191 into contact with fiberous and/or particulate biodegradable resin 50, wherein the sticker contains compatible polymer compatible with both natural fiber and biodegradable resin and contains polyvinyl alcohol; a mixing process in which the natural fiber mixture is obtained by mixing the biodegradable resin stuck with the compatible polymer and the natural fiber; and a molding process in which the natural fiber moldings are obtained by heating/compressing the natural fiber mixture.
