PROBLEM TO BE SOLVED: To provide a cartridge for a photosensitive recording medium which can prevent exposure of the photosensitive recording medium by reliably locking a shutter while the shutter is closed, and has high reliability. SOLUTION: The cartridge includes: a cartridge body 11 housing a disk-like photosensitive recording medium 4 and having apertures 18 and 19 for exposing a part of the photosensitive recording medium 4 to an external part; a shutter 13 assembled in the outer side of the cartridge body 11 and opening and closing the apertures 18 and 19; and a locking member 63 locking the shutter in a closing position, wherein a hooking part 63f being a slope formed so as to be sloped in the closing direction of the shutter 13 is formed in the locking member 63, and an engagement slope 56f which is formed to be nearly parallel to the hooking part 63f and fits to the hooking part 63f in a state in which the shutter 13 is positioned in the closing position, is formed in the shutter 13.
