This method for manufacturing a cylindrical relief-printing plate by wrapping a printing-plate sheet around a cylindrical support provides a cylindrical relief-printing plate that exhibits high joint strength at the ends thereof such that the printing plate does not come loose, even when laser engraving is applied. Said method includes the following steps: (i) a step in which a printing-plate sheet that has, on the surface thereof, an uncured photosensitive-resin layer with a compressive strength at 25 DEG C between 1.0 and 3.0 kgf/cm2, inclusive, is produced; (ii) a step in which said printing-plate sheet is wrapped around a cylindrical support such that the edge where the wrapping starts and the edge where the wrapping ends overlap; and (iii) a step in which the overlap section where the edge where the wrapping starts and the edge where the wrapping ends overlap is pressure-bonded via the application of pressure at a temperature between 10 DEG C and 40 DEG C, inclusive. This method may also include a step (iv), after step (iii), in which the uncured photosensitive-resin layer is light-cured and may also include a step (v), after step (iv), in which the overlap section is ground, polished, and/or machined.
