PURPOSE: To prevent the distorted winding of a roll body which is being transported by simple structure without necessitating special work for an external body and the roll body which are used at present nor leaving attachment such as adhesive on the roll body.

CONSTITUTION: The roll body 1 constituted by winding a long photosensitive material 2 on a winding tube 3 is housed in the external body 4. As for the roll-state photosensitive material constitued by drawing the leading edge of a pulled-out part 2A pulled out from the roll body 1 from the mouth part 5 of the external body 4; an adhesive tape 7 having re-striping resistance is stuck to a V-shaped opposed area where the back surf ace of the pulled-out part 2A is opposed to the surface of the roll body 1 positioned near the part 2A so that the adhesive power to the pulled-out part is made stronger than that to the surface of the roll body 1.
