Abstract:
1. A method for manufacturing a concave-convex pattern comprising: heating a sheet-like member having a concave-convex pattern block on at least one of surfaces of the sheet-like member to give flowability to the sheet-like member by heating; compressively bonding the sheet-like member to a substrate via a reverse concave-convex pattern layer, the reverse concave-convex pattern layer being formed on the one of the surfaces to continue over two or more concaves of the concave-convex pattern block so that the reverse concave-convex pattern layer meshes at least partially with the concave-convex pattern block, the one of the surfaces having the concave-convex pattern block; removing the sheet-like member after the compressively bonding so that at least the reverse concave-convex pattern layer is left on the substrate; and transferring a pattern shape of the reverse concave-convex pattern layer to a surface of the substrate after removing the sheet-like member;
