Zusammenfassung:PROBLEM TO BE SOLVED: To rapidly engrave a fine design pattern on a pattern pressing roll at low cost. SOLUTION: A pattern pressing roll manufacturing method comprises a first step of engraving the outer circumferential surface of a roll by irradiating a substantially flat outer circumferential surface of the roll at least outer circumferential surface layer of which is formed of silicone rubber with first laser beams of long wavelengths, and a second step of irradiating the outer circumferential surface of the roll with second laser beams of wavelengths shorter than the wavelengths of the first laser beams and of the spot diameter smaller than that of the first laser beams.
