Abstract

A glass substrate includes at least one selected from the group consisting of Li, Na, K, Mg, Ca, Sr, Ba and Zn as a reaction factor component, and includes a surface depletion layer at a surface side of the glass substrate. A total molar concentration (mol/cm) of the reaction factor component in the surface depletion layer is decreased relative to an inside of the glass substrate. A total depletion amount (mol/cm) of the reaction factor component in the surface depletion layer is 1.00×10or more. The glass substrate has a refractive index (n) of 1.68 or more.
