    Abstract: To provide an article with a water and oil repellent layer, which is excellent in friction resistance.
    The article with a water and oil repellent layer of the present invention comprises a substrate, a water and oil repellent layer consisting of a hydrolyzed condensation product of a compound represented by the formula [A-(OX)m-]jY1[—Si(R)nL3-n]g, and a silicon oxide layer containing alkali metal atoms that exists between the substrate and the water and oil repellent layer, wherein the average value of the concentration of alkali metal atoms in a predetermined area in the silicon oxide layer is at least a predetermined value. In the formula, X is a fluoroalkylene group, m is at least 2, j, g, and k are at least 1, and Y1 and Y2 are linking groups, R is a monovalent hydrocarbon group, L is a hydrolyzable group or hydroxy group, n is 0 to 2, A is a perfluoroalkyl group or —Y2[—Si(R)nL3-n]n. When A is —Y2[—Si(R)nL3-n]k, j is 1, and when A is a perfluoroalkyl group and j is 1, g is at least 2.
