The master film is provided with a second micro concave-convex structure formed on a surface that faces the first micro concave-convex structure, the second micro concave-convex structure is made of a cured curing resin, and has a reverse shape of the first micro concave-convex structure, and the optical film and the master film are separable from each other.
