To provide a cylindrical flexographic printing original plate capable of undergoing laser engraving, which suppresses occurrence of scum when a relief image is produced by directly performing the laser engraving, enables the scum to be removed with ease, makes an engraved shape excellent, reduces tackiness of a printed surface, makes printing quality excellent, and which enables production of an easy-to-handle printing plate.

The cylindrical flexographic printing original plate capable of undergoing the laser engraving is characterized in that it is a laminate wherein a seamless cushion layer (B) and a photosensitive resin hardened matter layer (C) capable of undergoing the laser engraving are laminated on a cylindrical support (A) in this order, that the cushion layer includes air bubbles having partitions, and that the photosensitive resin hardened matter layer (C) contains inorganic porous materials (f).
