Claim Text:
1. A substrate for optics comprising a fine-structure layer including dots comprised of a plurality of convex portions or concave portions extending in a direction of from a main surface of a substrate to outside the surface, wherein the fine-structure layer forms a plurality of linear dot lines in which the plurality of dots is arranged with a pitch Py in a first direction in the main surface of the substrate and centers of the plurality of dots are on a straight line in the first direction, while the plurality of linear dot lines form a plurality of dot lines arranged with a pitch Px in a second direction orthogonal to the first direction in the main surface of the substrate, and one of the pitch Py and the pitch Px is a constant interval of nano-order, while the other one is an inconstant interval of nano-order, or both are inconstant intervals of nano-order.
