Zusammenfassung:	There is demand for a novel method for manufacturing a RebD crystallized product. The present invention provides a method for manufacturing a RebD-containing crystallized product, including: a step for mixing a stevia plant-derived crude product having a total steviol glycoside content of 50-95 mass%, and containing at least RebA and RebD, into a solvent containing methanol or ethanol so that the supersaturation of RebD at 10°C is at least 10 and the supersaturation of RebA at 10°C does not exceed 18, and adjusting a crystallization solution; and a step for cooling the crystallization solution under stirring and causing RebD to precipitate.
