A light-shielded photosensitive material roll equipped with adapters is provided in which a photosensitive material sheet, which has been unwound once, can be wound up again smoothly. The photosensitive material roll, which can be mounted in a predetermined machine, includes: (a) a hollow, cylindrical winding core; (b) an elongated photosensitive material sheet wound-up on the winding core; (c) an annular member including a cylindrical portion inserted in an opening of the core, and a flange portion extending in a radial direction from one end of the cylindrical portion; (d) a ring-shaped light-shielding sheet disposed between the annular member flange portion and the core; and (e) an adapter including an adapter tube portion inserted into the annular member cylindrical portion, and an adapter flange portion extending in a radial direction from one end of the adapter tube portion. The light-shielding sheet is partially adhered to the adapter flange portion.
