PROBLEM TO BE SOLVED: To obtain a low-cost light-shielding rolled photosensitive material packed body, less liable to cause failures in light shielding due to damages such as the cutting of a light shielding leader, horizontal dislocation and the separation of light shielding members other than the light-shielding leader. SOLUTION: A light-shielding leader 4 consists of an inner leader part 41 and an outer leader part 42. The width of the inner leader part 41 is larger than that of a long-length photosensitive material 3 and the part 41 has a length, which is larger than the interval between the inner walls of the outer peripheral parts of light-shielding flanges 2 and smaller than the interval between the outer edges of the peripheral parts of the flanges 2. The width of the outer leader part 42 is larger than that of the inner leader part 41, the length of the part 41 in the winding direction is larger than the peripheral length of the rolled photosensitive material 3, and the length of the outer leader part 42 in the winding direction is larger than the peripheral length of the light- shielding flanges 2.
