This process for producing a purified polysaccharide comprises bringing a polysaccharide solution obtained by dissolving a polysaccharide in a liquid which contains an ionic liquid into contact with a solidification liquid which contains an ionic liquid, and thus dry-wet spinning the polysaccharide, wherein: the ionic liquid concentration of the solidification liquid is 0.4 to 70wt%; and the distance (D) from the site at which the polysaccharide solution is ejected into fiber-shaped products to the site at which the fiber-shaped products come into contact with the solidification liquid is 50 to 120mm. |
