Abstract
To provide a fine-structure layered product, and a preparation method of a fine-structure layered product using the fine-structure layered product for enabling a fine concavo-convex structure excellent in environmental resistance, weather resistance and long-term stability to be formed with a large area and high productivity, and provide a manufacturing method of a fine-structure product for enabling a large area to be made with high productivity, a fine-structure layered product of the invention is provided with a substrate, a resin layer that is formed on one main surface of the substrate and that has a fine concavo-convex structure on its surface, and an inorganic layer that is provided on the fine concavo-convex structure of the resin layer and that contains a sol-gel material having a fine concavo-convex structure in a shape associated with the fine concavo-convex structure of the resin layer, where a fluorine element concentration (Es) in a region on the inorganic layer side of the resin layer is higher than an average fluorine concentration (Eb) in the resin layer.
