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).
