Abstract: PROBLEM TO BE SOLVED: To provide a method for producing a thin film consisting of nanosheet monolayer film(s) and use of the thin film obtained thereby.SOLUTION: A method for producing a thin film consisting of nanosheet monolayer film(s) by a spin coat method comprises a step of preparing an organic solvent sol formed by allowing nanosheets obtained by the exfoliation of an inorganic layered substance to be dispersed in an organic solvent; and a step of dropping the organic solvent sol onto a substrate and rotating the substrate using a spin coater. Preferably, the nanosheet size, the organic solvent sol concentration and the spin coater rotation speed are controlled.
