SANITARY FACILITY MEMBER
To provide a sanitary facility member with superior dirt-removal properties and lasting effectiveness of the dirt-removal properties.SOLUTION: A sanitary facility member includes a base material including metal elements in its surface, a metal oxide layer formed on the base material, and an organic layer provided on the metal oxide layer. The metal elements are one or more selected from a group consisting of Cr, Zr and Ti, and the organic layer is present on a surface of the sanitary facility member. The sanitary facility member has the metal element M, a phosphorous atom P, an oxygen atom O, and a carbon atom C to be detected when its surface is measured by X-ray photoelectric spectroscopy XPS, and also has fragments, represented by a general formula R-X, to be detected when measured by time-of-flight secondary ion mass spectroscopy (where R is a hydrocarbon group or a group having an atom other than carbon at one or two positions in the hydrocarbon group, and X is one selected from a phosphonic acid group, a phosphate group, and a phosphinic acid group).SELECTED DRAWING: Figure 1
【課題】汚れの易除去性およびその持続性に優れた衛生設備部材の提供。【解決手段】表面が金属元素を含む基材と、基材上に形成された金属酸化物層と、金属酸化物層上に設けられた有機層とを含む衛生設備部材であり、金属元素は、Ｃｒ、Ｚｒ、及びＴｉからなる群より選ばれる１種以上であり、有機層は前記衛生設備部材の表面に存在するものであり、衛生設備部材は、その表面を、Ｘ線光電分光法ＸＰＳによって測定したときに、前記金属元素Ｍと、リン原子Ｐと、酸素原子Ｏと、炭素原子Ｃが検出され、かつ、飛行時間型二次イオン質量分析法によって測定したときに、一般式Ｒ‐Ｘ（Ｒは炭化水素基または炭化水素基内の１ないし２個所に炭素以外の原子を有する基で、Ｘはホスホン酸基、リン酸基、及びホスフィン酸基からなる１種）で表されるフラグメントが検出されるものである。【選択図】図１
