Abstract: There is provided a new and improved master manufacturing method, master, and optical body enabling more consistent production of optical bodies having a desired haze value, the master manufacturing method including: forming a first micro concave-convex structure, in which an average cycle of concavities and convexities is less than or equal to visible light wavelengths, on a surface of a base material body that includes at least a base material; forming an inorganic resist layer on the first micro concave-convex structure; forming, on the inorganic resist layer, an organic resist layer including an organic resist and filler particles distributed throughout the organic resist; and etching the organic resist layer and the inorganic resist layer to thereby superimpose and form on the surface of the base material a macro concave-convex structure and a second micro concave-convex structure.
