This invention provides a structure, which has surface shape and properties required of a structure having, for example, light reflection preventive properties and light transmission improving properties and particularly has surface scratch resistance and the like, and a composition, which can form a good structure having the specific structure and possessing the specific properties, and a composition which can form a structure having better light reflection preventive properties and light transmission improving properties and having a high aspect ratio. Specifically, the structure has on its surface a convex part having an average height of not less than 100 nm and not more than 1000 nm or a concave part having an average depth of not less than 100 nm and not more than 1000 nm, the convex part or the concave part being present at an average period of not less than 100 nm and not more than 400 nm at least in a certain one direction and is characterized in that the structure has been produced by polymerizing an (meth)acrylic polymerizable composition by light irradiation, electron beam irradiation and/or heating and has a storage modulus of not less than 0.5 GPa at 180°C or above. |
