Abstract

Provided are a master in which a more complicated microstructure is formed, a transferred object obtained by using the master, and a method of producing the master. A plurality of concave-convex groups each including a plurality of concavities or convexities are provided on a base material apart from each other. Average widths of areas occupied by the concavities or convexities at a surface of the base material are smaller than or equal to a wavelength belonging to a visible light band. Formed lengths of the concavities or convexities from the surface of the base material in each of the concave-convex groups each belong to any of at least two or more groups having different central values.
