The concavo-convex structure has a plurality of structures (21) that are periodically arranged and include at least one of a concave element and a convex element. A plurality of annuli arranged along a radial direction of the substrate are formed on the substrate. Each of the plurality of annuli includes, along the radial direction, a first region (R1) and a second region (R2) having a phase smaller than that of the first region. The plurality of structures include a plurality of first structures disposed in the first region and a plurality of second structures disposed in the second region. A base layer (22) is provided between the substrate and at least one of the plurality of second structures.
