Method for producing a gel having a desired strength, by performing a step of removing a part or all of a solvent. Method for producing a gel containing a water-soluble organic polymer (A), a silicate salt (B), and a dispersant (C) for the silicate salt, including a desolvation step of removing a part or all of one or more solvents selected from the group consisting of water and a water-soluble organic solvent in the gel, or gelling a gel-forming composition containing the water-soluble organic polymer (A), the silicate salt (B), the dispersant (C) for the silicate salt, and one or more solvents selected from the group consisting of water and a water-soluble organic solvent and removing a part or all of the solvent in the composition.
