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 an alkaline earth metal element, and the ratio of the molar concentration of the alkaline earth metal element in the undercoat layer to the molar concentration of silicon in the undercoat layer is from 0.005 to 5.

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 of boron and phosphorus, and
the ratio of the total molar concentration of boron and phosphorus in the undercoat layer to the molar concentration of silicon in the undercoat layer is from 0.003 to 9.
