ABSTRACT:
A convex/concave pattern-forming stamp which is capable of making recesses of a convex/concave pattern uniform in depth and preventing deformation and peeling of portions of the convex/concave pattern at the same time. The stamp has on a surface thereof an annular area formed with protrusions for forming a convex/concave pattern in a resin layer on a surface of a disk-shaped substrate by being pressed against the resin layer. Protrusions for dispersing a pressure applied to the resin layer when the stamp is pressed against the resin layer are formed in at least one of an outer area located radially outward of the annular area and an inner area located radially inward of the annular area.
