Abstract: This water-repellent, oil-repellent member is obtained via a method comprising: a step for wet-coating a substrate surface with a solution containing an organic silicon compound comprising multiple silanol groups and a solvent; a step for drying the solvent to form a primer layer; a step for wet-coating the primer layer with a solution containing a fluorine-containing compound and a solvent, followed by drying the solvent, or dry-coating with the fluorine-containing compound obtained by evaporating the solvent from the solution; and a step for curing the fluorine-containing compound to form a water-repellent, oil-repellent layer. The water-repellent, oil-repellent member is obtained by providing, on various substrates, a primer layer of a specific thickness containing, as a main component, an organic silicon compound comprising multiple silanol groups, followed by providing, on the primer layer, a water-repellent, oil-repellent layer of a specific thickness containing, as a main component, the cured fluorine-containing compound according to the above mentioned method. It is thus possible to stably and simply form a water-repellent, oil-repellent coating exhibiting superior abrasion resistance on various substrates, and the primer layer and water-repellent, oil-repellent layer can be applied using a room-temperature (25° C.) process.
