ABSTRACT:
An article with a silica-based film that contains an organic material and has excellent mechanical strength. This article includes a substrate and an organic-inorganic composite film that is formed on the surface of the substrate. The organic-inorganic composite film contains silica as its main component. A value of (0.19A+0.03) or lower (A denotes the film thickness [μm]) is obtained through X-ray diffraction analysis on the organic-inorganic composite film, with the X-ray incident angle being fixed at 1° with respect to the surface of the organic-inorganic composite film, when the intensity of a peak at a diffraction angle of 3° to 10° is standardized using the intensity of a halo pattern peak at a diffraction angle of 20° to 30°. A value of 0.25 or lower is obtained through Fourier transform infrared spectroscopy analysis on the organic-inorganic composite film, when the intensity of a peak at around 950 cm−1based on a Si—OH group is standardized using the intensity of a peak at around 1100 cm−1based on a Si—O—Si bond.
