In order to improve the scratch resistance of an antireflective article having a moth-eye structure, an antireflective article is provided that has fine protrusions densely arranged therein, and has the interval between adjacent fine protrusions being no more than the shortest wavelength in the wavelength band for antireflection. At least some of the fine protrusions are fine protrusions having a plurality of apexes.

In order to improve the scratch resistance of an antireflective article having a moth-eye structure, an antireflective article is provided that has fine protrusions densely arranged therein, has the interval between adjacent fine protrusions being no more than the shortest wavelength for an electromagnetic wavelength band for antireflection, and wherein: the fine protrusions are arranged in a non-lattice shape in the planar view; and mesh division lines formed upon the valley sections between each adjacent fine protrusions and surrounding each fine protrusion match Voronoi tessellation having the center of gravity of the fine protrusions, in the planar view as the generating point therefor, in at least one area of the antireflective article.
