摘要： A package of a rolled photosensitive material comprising a core, a rolled photosensitive material wound around the core, a light-shielding leader which shields the peripheral face of the rolled photosensitive material from light, a pair of side plate inner rings which shield both sides of the rolled photosensitive material, an adhesive layer which adheres each of the side plate inner rings to the core, a caulking part which is formed on the adhesive layer and which enters the core, and a light-shielding part which is formed on the side plate inner ring, which adheres to the caulking part, and of which the inner end is positioned on the inner part from the surface of the core. The package can ensure light-shielding at the side plate inner ring simply and inexpensively, and having a sufficient adhesive strength between the side plate inner ring and the core.
