PROBLEM TO BE SOLVED: To provide stimulation-responding gel, which is gel having sufficient strength and elongation as a material, high water-swelling property in a wide temperature range, and flexibility even in a dried state, and which exhibits changes in the swelling-shrinking behavior in a gel state by external stimulation such as temperature, salt concentration and pH. SOLUTION: This organic-inorganic composite gel is provided, comprising a three-dimensional network formed of a polymer of radical polymerizable monomers (A) and a water-swelling clay mineral (B), and water (C) incorporated therein. The radical polymerizable monomers (A) contain 99 to 40 mol% of hydrophilic monomers (A1) which are hydrophilic before polymerization but change into hydrophobic in a homopolymer thereof, and 1 to 60 mol% of hydrophilic monomers (A2) which are hydrophilic before polymerization and remain hydrophilic in a homopolymer thereof.
