To provide microwell films for bioassay suitable for a 'unimolecular enzyme assay' method and methods of manufacturing the films, a microwell film for bioassay is comprised of at least a substrate (), and a resin layer () having microwells on its surface provided on one main surface of the substrate (), where in the substrate () and the resin forming the resin layer (), an absorption coefficient at each of wavelengths of 350 nm to 800 nm is 0.01 μmor less.

Microwell film for bioassay, photosensitive resin composition for formation of the microwell film for bioassay, and method of manufacturing the microwell film for bioassay

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.
