Abstract
A cleaning solution is used, in a transparent antireflective structure that has, on one surface thereof, a plurality of convexities formed at a period equal to or shorter than wavelength in a visible light range, and that prevents, at the one surface, reflection of light entering the one surface, to clean a concavity defining a region between adjacent two of the plural convexities, the cleaning solution having a pH of 10.00 or more.
