To provide a refrigerator capable of reducing power consumption.

In a refrigerator 1 in which a compressor 10 operating a refrigeration cycle by circulating a refrigerant, a machine room condenser 20 disposed between a first refrigerant pipe 22 and a second refrigerant pipe 23 which constitute at least a part of a high temperature portion of the refrigeration cycle and in which the refrigerant is circulated, and a machine room air blower 25 for cooling the machine room condenser 20, are disposed in a machine room 6, the machine room condenser 20 is composed of a flat microtube 21 in which a plurality of refrigerant thin paths 21 are arranged in parallel with each other, the microtube 21 is spirally disposed around the first refrigerant pipe in a state that the arrangement direction of the thin paths 21 are agreed with each other in the axial direction where the first refrigerant pipe 22 is extended, and is connected with the second refrigerant pipe 23 at its outer peripheral end, and the machine room air blower 25 is faced to an axial end face of the machine room condenser 20.
