An article with a surface layer, that is excellent in fingerprint stain removability, friction resistance, and adhesion to a protective film of the surface layer. The article includes a base material and a surface layer provided on the surface of the base material. The surface layer contains groups having —O— between carbon-carbon atoms of a fluoroalkyl group with two or more carbon atoms and has a normalized F intensity in a range of 0.38 to 0.53, where the normalized F intensity is obtained by preparing a glass containing 4.96 mass % of fluorine atoms as a standard sample, measuring, by an X-ray fluorescence spectrometer, the fluorine atom intensity in the surface layer and the fluorine atom intensity in the standard sample, respectively, and dividing the fluorine atom intensity in the surface layer by the fluorine atom intensity in the standard sample.

The invention provides a method for etching which is intended for reducing the thickness of a glass substrate, and which attains a high etching rate and is capable of inhibiting haze generation on the glass substrate surface. The invention relates to a method for etching a glass substrate surface, comprising etching the glass substrate surface in an amount of 1-690 &#x3bc;m in terms of etching amount, in which the etching is conducted with an etchant having an HF concentration of 1-5 wt % and an HCl concentration of 1 wt % or higher.

To provide a process for producing a reliable substrate in good yield, by suppressing bleeding of boric acid from a green sheet comprising a powder of borosilicate glass to improve printability of a conductive pattern thereby to prevent disconnection. A process for producing a substrate which comprises firing a green sheet comprising a powder of borosilicate glass, wherein the powder is one prepared by holding borosilicate glass before pulverization, at a temperature higher by at least 30&#xb0; C. than the glass transition temperature and lower by at most 50&#xb0; C. than the softening point of the borosilicate glass for at least 3 hours in the atmosphere, followed by pulverization.
