Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for producing a mannan oligosaccharide useful as a functional food material or an intermediate for pharmaceuticals, especially a mannan oligosaccharide having a molecular weight of about 1,000-6,000 in high purity and efficiency. SOLUTION: The method for producing a mannan oligosaccharide comprises the hydrolysis of a mannan-based natural polysaccharide in an aqueous solvent at 150-450°C, or the hydrolysis of a mannan-based natural polysaccharide in an aqueous solvent containing carbon dioxide at 120-450°C.
