A case for accommodating a disc cartridge is disclosed which is capable of reliably protecting a disc and enabling the disc cartridge to easily be loaded/unloaded, which can arbitrarily be designed and the cost of which can be reduced. The case for accommodating a disc cartridge incorporates: a frame formed by integrating first and second frames disposed opposite to each other and a connection member for connecting the base portions of the first and second frames to each other; and a cover formed by integrating first and second cover plates which are inserted into a space between the first and second frames to be opposite to each other and a connecting cover member for connecting the base portions of the first and second cover plates to each other. The frame is made of the synthetic resin having excellent impact resistance as compared with the cover. The cover is made of the synthetic resin having light permeability.
