Abstract
A stamper of an embodiment includes: a base portion having a main surface; and a plurality of guides arranged on the main surface in mutually different first and second directions and serving as references of arrangement of a plurality of self-assembled dots. A distance between the guides in a third direction is within a range of an integer m±0.05 times of a pitch of the plural self-assembled dots. The third direction corresponds to a third vector obtained by combining a first vector corresponding to the arrangement of the guides in the first direction and a second vector corresponding to the arrangement of the guides in the second direction. A distance between the plural guides in the first direction falls out of a range of an integer m±0.15 times of the pitch of the plural self-assembled dots.
