PROBLEM TO BE SOLVED: To provide a simplified energy-saving method for producing a hydrogel containing a clay mineral and having essentially high clay content and high mechanical strength such as tensile strength and compression strength. SOLUTION: The hydrogel containing a clay mineral is produced by adding a water-soluble organic monomer or the monomer and a polymerization initiator and a catalyst to an aqueous dispersion of a water-swelling clay mineral dispersed in water or a mixture of water and an organic solvent, charging the obtained mixture to a container, rotating the container around an external axis while rotating on its own axis to uniformly disperse the components in the mixture and carrying out the polymerization reaction.
