PROBLEM TO BE SOLVED: To provide a transparent novel material/new technology exhibiting not only high thermostability but also excellence flexibility, surface smoothness, dimensional stability and gas barrier properties. SOLUTION: An inorganic layered compound film containing inorganic layered compound particles aligned and exhibiting high surface smoothness, high dimensional stability, high transparency, excellent flexibility, excellent gas barrier properties and high heat resistance is obtained by dispersing an inorganic layered compound of high transparency and a small amount of water-soluble polymer of high transparency in water or a liquid composed mainly of water to thereby obtain a homogeneous dispersion containing no agglomerates, and thereafter applying this dispersion onto a support with flat and water-repellent surface to thereby effect deposition of inorganic layered compound particles and separating the liquid as dispersion medium according to any of various solid liquid separating techniques, for example, centrifugal separation, filtration, vacuum drying, vacuum freeze drying, heating evaporation, etc., to thereby attain forming into a film, optionally followed by methods of drying/heating/cooling, etc., to thereby attain detachment from the support.
