PROBLEM TO BE SOLVED: To provide a structure which satisfies conditions, required for a structure having optical properties such as antireflection and transmission enhancement properties, which includes not only a surface shape but also surface physical properties, or specifically mechanical strength such as surface scratch resistance, dirt repelling capability, and dirt wipability, and to provide a material capable of forming such a structure.SOLUTION: Described is a structure with concave portions having an average height or depth of 100 nm to 1000 nm, inclusive, on a surface thereof, where a corresponding convex portion or the concave portion appears at every average interval of 50 nm to 400 nm, inclusive, along one direction at least. The structure is made by curing a polymerizable composition containing a (meth)acrylate compound by means of light or electron beam irradiation and/or heat. The polymerizable composition contains a fluorochemical surfactant. An antireflection body forming material, which is the polymerizable composition for forming the structure, containing a (meth)acrylate compound and a fluorochemical surfactant is also described. |
