Abstract: To provide a water/oil repellent layer-provided substrate having improved long-term reliability of abrasion resistance, and a method for producing it.
A water/oil repellent layer-provided substrate comprising a substrate, an undercoat layer formed on the surface of the substrate, and a water/oil repellent layer formed on the surface of the undercoat layer, in this order, wherein the alkali deficiency index is higher than 0.0, as determined by a depth profile obtained by X-ray photoelectron spectroscopy (XPS) by C60 ion sputtering from the side of the surface of the water/oil repellent layer, taking the total concentration of fluorine, silicon, aluminum, alkali metal elements and oxygen as 100 at %.

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/cm3) 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/cm2) of the reaction factor component in the surface depletion layer is 1.00×10−8 or more. The glass substrate has a refractive index (nd) of 1.68 or more.
