In a disk cartridge, a disk-shaped medium is rotatably accommodated in a case formed by combining both halves vertically using a coupling rib provided on at least one substrate surface. A disk cartridge characterized in that a part of the outer peripheral wall of the upper and lower halves near the intersection is provided so that they do not come into contact with each other. (2) The disk cartridge according to item 1, wherein projections and depressions for fitting are formed on opposing surfaces of the upper and lower halves that are not in contact with each other on a part of the outer peripheral wall of the upper and lower halves.
