SANITARY EQUIPMENT PART
A part includes a base material and a surface layer thereon, wherein a curved surface of the part has a root mean square height (Sq) of 0.03 μm to 1 μm, a skewness (Ssk) of −1 to 5 or less, and an autocorrelation length (Sal) of 10 μm to 65 μm; and the surface layer is water-repellent, and exhibits a sputtering time of 5 minutes or less, the sputtering time being a time taken from the start of the sputtering to an end point of the surface layer, and the end point being defined, in a profile obtained by an XPS depth direction analysis of the surface layer, as a point where a difference of an absolute value between a carbon atom concentration at a certain measurement point and a carbon atom concentration at a measurement point just prior to the certain measurement point is 1.0 at % or less.
