Beschreibung
Zusammenfassung:	An object of the present invention is to provide a chemically strengthened glass having enhanced surface strength and bending strength. The present invention relates to a chemically strengthened glass having a compressive stress layer formed on a surface layer thereof by an ion exchange method, in which a straight line obtained by a linear approximation of a hydrogen concentration Y in a region of a depth X from an outermost surface of the glass satisfies a specific relational equation (I) in X=0.1 to 0.4 (μm), and an edge surface connecting main surfaces on a front side and a back side of the glass has a skewness (Rsk) measured based on JIS B0601 (2001) being −1.3 or more.
