PROBLEM TO BE SOLVED: To provide a refrigerator capable of reducing power consumption and storing foods in a long term by using a heat pipe in combination for cooling of a cooling chamber, thereby improving the cycle efficiency, further minimizing the load of a cooling chamber cooler to raise the evaporation temperature, and reducing the frost formation quantity to the cooler to keep a constant-temperature and high-humidity atmosphere. SOLUTION: A refrigeration cycle is formed by a two-stage compressor 13, a freezing cooler 9 connected to a refrigerant passage switching valve provided on the outlet side of a condenser through a decompression device, and a decompression device and the cooling cooler 11 provided in parallel to the circuit of the freezing cooler. A suction pipe of the cooling cooler is introduced into the intermediate pressure part of a compressor case, so that the refrigerant is sucked to the high stage-side compression part in combination with the refrigerant sucked from the freezing cooler to the low stage-side compression part, compressed and discharged. A heat pipe cooling plate 15 cooled by the cooling force of the cooling cooler 11 is arranged in a storage space 2 cooled by forcedly circulating the cold air from the cooling cooler by a fan 12.
