Summary: | To provide a water/oil repellent layer-provided article of which the water/oil repellent layer is excellent in abrasion resistance, and a method for producing it.A water/oil repellent layer-provided article 10, comprising a substrate 12, a water/oil repellent layer 16 comprising a hydrolyzed condensate of a fluorinated compound having a hydrolyzable silyl group, and a silicon oxide layer 14 containing alkali metal atoms, present between the substrate 12 and the water/oil repellent layer 16, wherein in the silicon oxide layer 14, the average concentration of the alkali metal atoms in a region with a depth from the surface in contact with the water/oil repellent layer 16 of at least 0.1 nm and at most 0.3 nm, is at least 2.0×1019atoms/cm3. |
