PROBLEM TO BE SOLVED: To provide a refrigerator capable of surely preventing dew condensation by using high pressure side piping of a refrigerant circuit even when a refrigerant on which a high pressure side of a refrigerant circuit is operated at a supercritical pressure is used. SOLUTION: In this refrigerator 1 using the high pressure side piping of the refrigerant circuit to prevent dew condensation of a main body, the refrigerant circuit is operated at a supercritical pressure at its high-pressure side, a refrigerant temperature of an outlet of a frame pipe 30 as the high-pressure side piping is detected by an outlet refrigerant temperature sensor 13 as an outlet refrigerant temperature detecting means, and the refrigerant temperature of the outlet of the frame pipe 30 is controlled at a dew-point temperature or higher or at an outside air temperature or higher, on the basis of the output of the outlet refrigerant temperature sensor 13.
