A disk cartridge is provided which, with a small number of parts, can reduce manufacturing costs and facilitate assembly. In particular, the disk cartridge can be assembled easily even if a disk medium is small-sized. Case members of a same configuration are superposed together so as to form a case. Shutter members of a same configuration are disposed so as to correspond to openings of the case members. A lock member and a spring member are provided in common for the two shutter members. The case members of the same configuration and the shutter members of the same configuration are used, and only one lock member and only one spring member are provided. Thus, a number of parts can be reduced, manufacturing costs can be reduced, and assembly can be facilitated.
