Abstract: The present invention relates to a chemically strengthened glass including alkali metal ions, having a thickness of 0.20 mm or smaller, and having a pair of major surfaces that are opposed to each other and have been subjected to a chemically strengthening treatment, in which at least one of the pair of major surfaces has a core roughness depth Sk of 0.90 nm or smaller and a mean summit curvature Ssc of 13.0×10−4/nm or smaller.

Abstract: An object of the present invention is to provide a chemically strengthened glass that can effectively suppress strength of a glass from being deteriorated even though performing chemical strengthening and has high transmittance (that is, low reflectivity). 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 the glass contains sodium and boron, and has a delta transmittance being +0.1% or more, and 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 in X=0.1 to 0.4 (μm).
