Abstract:
1. An inorganic film made of an inorganic laminar compound, wherein the inorganic film satisfies the below-defined Formula 1 and the below-defined Formula 2, Ha: the peak intensity in an X-ray diffraction measurement of the inorganic film Hb: the peak intensity in an X-ray diffraction measurement of a film resulting from the below-defined treatment (A) applied to the inorganic film Da: the spacing (Å) of the inorganic laminar compound constituting the inorganic film Db: the spacing (Å) of the inorganic laminar compound constituting the film resulting from the below-defined treatment (A) applied to the inorganic film treatment (A): treatment in which the inorganic film is heated at a temperature of 350° C. for 60 minutes under an atmosphere with a water vapor concentration of 50 g/cm
