A super absorbent polymer such as vinyl alcohol / acrylic acid copolymer and sodium polyacrylate is used, and water is added to and mixed with the super absorbent polymer having the required particle size. Utilizing the property of the water-absorbent polymer that absorbs water and solvent and hardly dissolves it. When water is added to this, it absorbs water in a short time and retains the absorbed water. The super absorbent polymer that absorbs water and swells has a predetermined water absorption ratio depending on its material, but it swells up to the maximum allowable.

It is flexible and can be deformed within a predetermined range and is appropriately determined. The outer surface of each particle of the superabsorbent polymer that has absorbed water by mixing and stirring in this manner is covered with the coating of the two-component reactive synthetic resin, and the particles are connected to each other. The thickness of the outer layer of the superabsorbent polymer particles is determined by the amount of the two-component reaction type synthetic resin to be mixed.
