Abstract: The present invention provides a method for efficiently producing monosaccharides, oligosaccharides, and furfurals from biomass. A biomass is hydrolyzed under conditions under which monosaccharides, oligosaccharides, and furfurals are produced while continuously supplying an aqueous suspension of the biomass from a supply port of a continuous primary hydrolysis device and moving the suspension through the device. A hydrolysis solution is continuously discharged from a discharge port of the continuous hydrolysis device, and a hydrolysis solution containing monosaccharides, oligosaccharides, and furfurals are extracted from an intermediate extraction port provided at any position between the supply port and the discharge port of the continuous primary hydrolysis device. The extracted hydrolysis solution is then subjected to secondary hydrolysis.
