In a disk cartridge having an imbalance of the flow of resin at the time of injection molding due to the lateral asymmetry of recesses on which a shutter slides, the thickness of each shell of the disk cartridge is balanced laterally by forming a projection in one region which is the left half of the shell or the right half of the shell with respect to the center line C of the shell and occupies a larger part of the area of a shutter sliding recess and by forming a recess in the other region which occupies a smaller part of the area of the shutter recess.
