Abstract: Disclosed is a faucet valve including: a first valve body including a first slide surface, and formed from an alumina-based sintered body; and a second valve body including a second slide surface, and formed from an alumina-based sintered body, the first and second slide surfaces at least partially being in contact with each other with water in between. At least part of the second slide body is formed from a first amorphous carbon layer. The hardness of the first amorphous carbon layer is equal to or less than that of the alumina-based sintered body forming the first valve body. In the first amorphous carbon layer, a ratio (ID/IG) of a D peak to a G peak, measured by Raman spectroscopy, is greater than 0.5 but less than 1.9.

Abstract: Provided is a wet area member for use in an indoor wet environment, comprising: a base member; and an amorphous carbon layer formed on a surface of the base member and mainly containing carbon atoms, wherein the amorphous carbon layer further contains hydrogen atoms, and the amorphous carbon layer contains the hydrogen atoms in a predetermined amount or more and has a density lower than a predetermined value so as to be capable of inhibiting sticking of water scale for a long period. This makes it possible to obtain a wet area member which exhibits a high stain release property and a high stain release durability.
