1. 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 comprises an oxide comprising silicon and at least one element selected from the group consisting of boron and phosphorus, and
a ratio of a total molar concentration of boron and phosphorus in the undercoat layer to a molar concentration of silicon in the undercoat layer is from 0.6 to 9.
