Summary:A high durable photocatalyst film which is a laminated film having a substrate film and, provided thereon via a protective layer, characterized in that a film exhibiting a specific performance in an accelerated weathering test by means of a sunshine weatherometer is used as the substrate film, an organic-inorganic graded film is used as the protective layer, and said laminated film exhibits a specific performance in an accelerated weathering test by means of a sunshine weatherometer; and a structure which has a surface being provided with said photocatalyst film thereon and exhibiting the photocatalytic function. La présente invention a trait à un film photocatalyseur longue durée qui est un film laminé présentant un film substrat, et disposé dessus via une couche de protection, caractérisé en ce qu'un film présentant une performance déterminée dans un essai de vieillissement accéléré est utilisé comme film substrat, un film profilé organique-inorganique est utilisé en tant que couche de protection, et ledit film laminé présente une performance déterminée dans un essai de vieillissement accéléré au moyen d'un dispositif d'insolation artificielle. L'invention a également trait à une structure comportant une surface munie dudit film photocatalyseur et présentant une fonction catalytique.
