Disclosed is an inorganic film comprising an inorganic laminar compound and a resin, characterized in that when an image observed with a transmission electron microscope of a cross section of the inorganic film including the thickness direction of the film is subjected to image processing to classify into 256 levels of shade on the gray scale, and subsequently, at each of arbitrary five or more points of the image-processed observed image, a straight line is drawn parallel with the thickness direction of the inorganic film from one surface of the inorganic film to the other surface, and then linear analysis is performed along each of the straight lines, the average value of standard deviations of degrees relative to the degree of each shade determined from the results of the linear analysis is 15 or less.
