Summary:PROBLEM TO BE SOLVED: To provide a method for producing a water-soluble polymer having a wide range of uses from a water-insoluble natural polymer. SOLUTION: This method for producing the water-soluble polymer derived from the water-insoluble natural high polymer is characterized by bringing the water-insoluble natural high polymer into contact with water at a high temperature under a high pressure in which the temperature is within the range exceeding 100 deg.C to 300 deg.C and the pressure is in a higher pressure state than the vapor pressure of water at the temperature and partially hydrolyzing the water-insoluble natural polymer.
