Abstract:
There are provided a master and a method for manufacturing the master, the master having, on its outer peripheral surface, a concave-convex structure in which concavities or convexities are continuously arranged with high precision. The master includes: a substrate with a hollow cylindrical shape or cylindrical shape; and a concave-convex structure on an outer peripheral surface of the substrate. The concave-convex structure has concavities or convexities continuously arranged at a predetermined pitch in a circumferential direction of the substrate. The concavities or convexities are arranged with a predetermined phase difference between circumferential rows adjacent in an axial direction of the substrate.
