1. A water/oil repellent member comprising a substrate, a primer layer disposed as a first layer on at least one surface of the substrate, and a water/oil repellent layer disposed as a second layer on the outer surface of the primer layer, the primer layer being a layer which is composed mainly of an organosilicon compound having a plurality of silanol groups in the molecule and has a thickness of 30 to 500 nm, wherein the primer layer contains 50 to 100% by weight of the organosilicon compound having a plurality of silanol groups in the molecule which has a silanol content of 0.002 to 0.042 mol/g, the water/oil repellent layer being a layer which is composed mainly of a cured product of a hydrolyzable fluorinated compound and has a thickness of 0.5 to 30 nm, the water/oil repellent layer having a surface resistivity of up to 1.0×10¹¹ Ω/sq on its outer surface.
