PROBLEM TO BE SOLVED: To provide a cartridge capable of effectively preventing a photosensitive recording medium from being exposed to light. SOLUTION: In the photosensitive recording medium cartridge, a distance between a light shielding plate 12 and the face, opposed to the light shielding plate 12, of a cartridge body 11 is gradually narrowed from the open position side of the shutter 13 to the close position side, an angle and a shape formed by the face, opposed to the light shielding plate 12, of the shutter 13 and the face, opposed to the cartridge body 11, of the shutter 13 is the same as an angle and a shape formed by the light shielding plate 12 on the close position and the outer surface of the cartridge body 11, and when the shutter 13 is on the close position, the shutter 13 is abutted on the light shielding plate 12 and the cartridge body 11 in respectively stuck states, so that the outer and inner apertures are closed and light can be tightly shielded.
