摘要

PROBLEM TO BE SOLVED: To improve scratch resistance of an antireflective article relating to a moth-eye structure.SOLUTION: An antireflective article 5 has an antireflection effect by a fine concavo-convex pattern on a surface thereof, in which large projections 16 are discretely and randomly disposed on the surface, and minute projections 15 are tightly arranged at an interval equal to or smaller than the shortest wavelength of a wavelength band of electromagnetic waves as a target of antireflection. The large projections 16 have height larger than height of the minute projections 15 arranged between the large projections 16 and have a wider root part than the longest wavelength of the wavelength band as a target of antireflection. Micro projections 16A are tightly arranged at an interval equal to or shorter than the shortest wavelength of the wavelength band of electromagnetic waves as a target of antireflection on at least a top part of the large projection.
