To provide a method for producing water-soluble polysaccharide from noncrystalline cellulose with good yields.SOLUTION: A method for producing water-soluble saccharide includes the steps of crushing a carbon raw material to prepare a carbon material for catalysts, and adding the carbon material for catalysts and noncrystalline cellulose to water for mixing. The method may further include the step of preparing the noncrystalline cellulose by making a cellulose raw material amorphous.SELECTED DRAWING: Figure 1 【課題】非結晶性セルロースから水溶性多糖類を収率よく製造する方法を提供することを課題とする。【解決手段】炭素原料を粉砕し触媒用炭素材料を作製する工程、及び触媒用炭素材料と非結晶性セルロースとを水に添加し混合する工程を含む、水溶性糖類の製造方法である。この非結晶性セルロースを、セルロース原料を非晶質化して作製する工程をさらに含むことができる。【選択図】図１
