To provide 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.An article with a surface layer, comprising a base material and a surface layer provided on the surface of the base material and characterized in that the surface layer contains groups having -O- between carbon-carbon atoms of a fluoroalkyl group with two or more carbon atoms, and the normalized F intensity obtained by preparing a glass containing 4.96 mass % of fluorine atoms (IGS G4 Fluoride Opal Glass manufactured by Bureau of Analysed Samples Ltd.) 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, is from 0.38 to 0.53.
