PROBLEM TO BE SOLVED: To impart directionality to an optical characteristic in antireflection article relating to a moth-eye structure.SOLUTION: In an antireflection article, minute projections 5 are arranged in close contact with one another, the interval between adjacent projections 5 is equal to or shorter than the shortest wavelength of a wavelength band subjected to antireflection. Each minute projection 5 inclines to the normal direction L1 of the surface of a base material 2. In terms of the direction of the inclination, adjacent minute projections 5 are substantially identical to each other.
