A saccharide recovering method for recovering saccharides from a saccharified slurry obtained after subjecting a slurry of cellulosic biomass to a hot water treatment and to provide a washing device for washing a saccharified slurry residue suited for conducting such a saccharide recovery method is provided. Saccharified slurry of cellulosic biomass is fed on a conveyor having a net conveyor belt, the saccharified slurry is dehydrated, washing water is sprayed to dissolve saccharides remaining in the residue into the washing liquid. The residue is washed by a plurality of washing water spraying units disposed in series in such a manner that the moving direction of the residue and the moving direction of the washing water are opposite to each other. The washing water having washed the residue is used as washing water for washing water spraying unit in the direction opposite to the moving direction of the conveyor.
