Abstract: Provided is a refrigerator. The refrigerator includes a main body defining a storage space, a cryogenic freezing compartment provided in the storage space, and a thermoelectric module assembly disposed at one side of the cryogenic freezing compartment so that the cryogenic freezing compartment is cooled to a temperature less than that of the storage space. The cryogenic freezing compartment includes a cryogenic case into which an insulation material is filled to be thermally insulated from the storage space and in which a cryogenic freezing space is defined, a case door opening and closing the cryogenic case, and a rail assembly connecting the cryogenic case to the case door and extending and contracted in multi-stages to allow the case door to be slid to be inserted and withdrawn. The rail assembly is mounted on the cryogenic case outside the cryogenic freezing space.
