PROBLEM TO BE SOLVED: To provide a miniature light-weight refrigerator with high energy efficiency. SOLUTION: The present refrigerator is adapted such that a Stirling freezer 1 is mounted on one side of a freezing cabinet 3 surrounded by a heat insulation member, and the cold air can cool the inside of the cabinet 3 through a thermal siphon 2. A condenser section 2a constituting the thermal siphon 2 is wound around a heat absorption section 4c of the Stirling freezer 1, and a liquid line 2c and a gas line 2d located at opposite ends of the condenser section are coupled with an evaporator section 2b passing through a wall of the cabinet 3 and disposed along a wall surface of a container section. The thermal siphon 2 is filled with a fluid such as CO2 and the like as a refrigerant, and the inside of the cabinet can be cooled therein by allowing these refrigerants to undergo phase transition upon its circulation in the thermal siphon. The present refrigerator is small-sized and is light weight with very low consumption of electric power, so that it can be installed adjoining to a seat for being mounted on a car, and it is easily carried so that it is suitable for a field leisure.
