Abstract A disk cartridge is composed of a case main body, and a disk holder for supporting a disk. The disk holder supports the disk by plural disk supporting parts protruded from a main body part and an arm part. A gripping part for gripping by finger is formed in the disk holder, and its thickness is set equal to that of the case main body. A locking part is provided in the gripping part, engaged with an engaging catch part provided in the notched part of the case main body, and thereby the deformation of the case main body to the outside is prevented during the insertion of the disk holder. The invention can improve the operability of a disk cartridge from which a disk is taken out, and to miniaturize the disk cartridge.
