Abstract: To provide a water/oil repellent layer-provided substrate having a water/oil repellent layer excellent in abrasion resistance, a deposition material and a method for producing a water/oil repellent layer-provided substrate.
The water/oil repellent layer-provided substrate of the present invention is a water/oil repellent layer-provided substrate comprising a substrate, an undercoat layer and a water/oil repellent layer in this order,



wherein the water/oil repellent layer comprises a condensate of a fluorinated compound having a reactive silyl group,
the undercoat layer contains an oxide containing silicon and at least one element selected from the group consisting of titanium, zirconium and aluminum, and
the ratio of the total molar concentration of titanium, zirconium and aluminum in the undercoat layer to the molar concentration of silicon in the undercoat layer is from 0.03 to 0.7.
