PROBLEM TO BE SOLVED: To provide a road sign pole having antifouling properties effective against a hydrophilic pollutant.SOLUTION: In a road sign pole to which hydrophobic antifouling properties are imparted, a road sign pole surface, on which a ratio of a CF bond is increased by plasma treatment using fluorine-containing gases, is formed. Preferably, in the road sign pole, a F/C ratio of the road sign pole surface, on which the ratio of the CF bond is increased, is in the range of 0.6-2.0. More preferably, a contact angle of water on the road sign pole surface, on which the ratio of the CF bond is increased, is set to be 100° or more.
【課題】親水性の汚染物質に対して有効な防汚性を有する道路標識柱を提供する。【解決手段】フッ素系ガスを用いたプラズマ処理によりＣＦ結合の割合を増加させた道路標識柱表面を形成してなる疎水防汚性を付与された道路標識柱、好ましくは、ＣＦ結合の割合を増加させた道路標識柱表面のＦ／Ｃの比率が０．６〜２．０である道路標識柱、さらに好ましくは、ＣＦ結合の割合を増加させた道路標識柱表面における水の接触角が１００?以上とする。【選択図】なし
