    Abstract: To provide glass to be used for chemically tempered glass, of which the strength is less likely to be reduced even when indentations are formed thereon. Glass for chemical tempering, which comprises, as represented by mole percentage based on oxides, from 62 to 68% of SiO2, from 6 to 12% of Al2O3, from 7 to 13% of MgO, from 9 to 17% of Na2O, and from 0 to 7% of K2O, wherein the difference obtained by subtracting the content of Al2O3 from the total content of Na2O and K2O is less than 10%, and when ZrO2 is contained, its content is at most 0.8%. Chemically tempered glass obtained by chemically tempering such glass for chemical tempering. Such chemically tempered glass has a compressive stress layer formed on the glass surface, which has a thickness of at least 30 μm and a surface compressive stress of at least 550 MPa.

    Abstract: A sensor module includes: a base member; at least one of a single or a plurality of sensors and vibrators arranged on the base member; and a protective member constituted of at least one flat surface or a curved surface, provided so as to cover the at least one of the sensors and the vibrators. A part or whole of the protective member is formed of a strengthened glass and the strengthened glass is a chemically strengthened glass or a physically strengthened glass.
