[Problem] The purpose of the present invention is to provide: an antifouling article to which fine substances such as dust and dirt do not easily adhere and which has excellent removal performance of adhering fine substances, while exhibiting good antifouling properties and dirt removal properties even in cases when fine substances have adhered thereto; and a method for producing the antifouling article. [Solution] An antifouling article which is characterized by having a cured condensed coating film of a perfluoropolyether group-containing silane represented by general formula (1) on the surface of a base and by having a fluorine concentration of the cured condensed coating film of 0.2-2.0 µg/cm2; and a production method which is suitable for obtaining the article. [Problème] Le but de la présente invention est de concevoir : un article antisalissure auquel les substances fines telles que la poussière et la saleté n'adhèrent pas facilement et qui permet d'éliminer aisément les substances fines y adhérant, cet article présentant de bonnes propriétés antisalissure et de bonnes propriétés d'élimination de la saleté même dans les cas où des substances fines y adhèrent ; et un procédé de production dudit article antisalissure. [Solution] L'invention concerne à ces fins un article antisalissure caractérisé en ce qu'il est muni d'un film de revêtement condensé réticulé constitué d'un silane contenant un groupe perfluoropolyéther représenté par la formule générale (1) sur la surface d'une base et en ce que la concentration en fluor du film de revêtement condensé réticulé est de 0,2 à 2,0 µg/cm2 ; et un procédé de production permettant d'obtenir l'article.
