Cover glass and glass laminate

A cover glass comprising a glass sheet and an inorganic film superposed on at least one surface of the glass sheet,

• wherein the glass sheet has a thickness of 1 mm or less,
• the inorganic film includes six or more layers formed by alternately superposing a film including a high-refractive-index material having a refractive index at 632-nm wavelength of 1.80 or higher and a film including a low-refractive-index material having a refractive index at the wavelength of less than 1.80, the films including the high-refractive-index material and the films including the low-refractive-index material each having a single-film thickness of 5 nm to 250 nm, the inorganic film having an overall thickness of 850 nm to 6,000 nm, and
• when the cover glass is placed on a horizontal platen so that one main surface of the cover glass is in contact with the platen and warpage amounts of the cover glass, which are amounts in which four corners of the cover glass have lifted from the platen, are measured with a gap gauge at 20° C., then an average value of the warpage amounts is 400 μm or less.

A glass laminate comprising a glass sheet and an inorganic film superposed on at least one surface of the glass sheet,

• an absolute value of product obtained by multiplying the overall thickness of the inorganic film by an overall stress value of the inorganic film is 220×103 nm·MPa or less.
