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.
