Abstract
There is provided a method for manufacturing a master on which an arbitrary pattern is formed, the method including: forming a thin-film layer on an outer circumferential surface of a base material in a round cylindrical or round columnar shape; generating a control signal corresponding to an object on the basis of an input image in which the object is depicted; irradiating the thin-film layer with laser light on the basis of the control signal and thereby forming a thin-film pattern corresponding to the object on the thin-film layer; and forming a pattern corresponding to the object on the outer circumferential surface of the base material using, as a mask, the thin-film layer on which the thin-film pattern is formed.
