A method for producing an organic-inorganic hybrid hydrogel includes mixing an aqueous solution (A) containing a water-soluble organic monomer (a1) and a phosphonic acid-modified hectorite (a2), a polymerization initiator (B), and a polymerization promotor (C) with each other. The aqueous solution (A) has a viscosity of 1,000 mPa.Math.s or less when stored at 50 C. for one week after preparation. The polymerization initiator (B) has a solubility of 50 g/100 ml or more in water at 20 C. The molar ratio [(B)/(a1)] of the polymerization initiator (B) to the water-soluble organic monomer (a1) is in the range of 0.01 to 0.1. The aqueous solution in the state immediately before being subjected to polymerization can be stored for a long term, and thus has excellent operation properties and has no restriction on the place where a hydrogel is produced, and therefore can be applied to various industrial uses.
