PROBLEM TO BE SOLVED: To obtain a glass component for water-area, capable of retaining antifogging properties for a long period immediately after use start, and usable in an indoor water-area circumstance.SOLUTION: A glass component for water-area is used in an indoor water-area circumstance. The glass component for water-area includes a glass substrate, and an amorphous carbon layer provided on the surface of the glass substrate, and containing a hydrogen atom and a carbon atom. The amorphous carbon layer has a density of less than 2.0 g/cm. The amorphous carbon layer further contains an oxygen atom, and in the amorphous carbon layer, an O/C ratio on the surface is larger than 0.3.SELECTED DRAWING: Figure 1 【課題】 本発明は、使用開始直後から長期にわたって防曇性を維持することが可能な屋内水まわり環境で用いられる水まわり用ガラス部材を得ることを目的としている。【解決手段】 本発明では、屋内水まわり環境で用いられる水まわり用ガラス部材を提供する。水まわり用ガラス部材は、ガラス基材と、ガラス基材の表面に設けられ、水素原子と炭素原子を含むアモルファスカーボン層と、を備える。アモルファスカーボン層において、密度は２．０ｇ／ｃｍ３未満である。アモルファスカーボン層は酸素原子をさらに含む。アモルファスカーボン層において、表面のＯ／Ｃ比は０．３よりも大きい。【選択図】 図１
