A disc cartridge capable of ensuring smooth sliding of a shutter on a casing while keeping a connection plate of the shutter from being abutted against or in contact with the casing, leading to a safe and increased-in-reliability sliding operation of the shutter. A lower plate of the shutter is provided with a holding pawl and a lower casing member is formed on an outer surface thereof with a slide groove, in which the holding pawl is slidably fitted. A side surface of the lower casing member on which the connection plate of the shutter is slid is outwardly projected beyond a side surface of an upper casing member on which the connection plate is likewise slid. Alternatively, the shutter is so formed that a bending angle between the lower plate and the connection plate is larger than that between an upper plate and the connection plate.
