There is disclosed a refrigeration apparatus including a cascade heat exchanger and capable of reducing the depth dimension of the apparatus itself without being influenced by the thickness dimension of an insulating material for covering the cascade heat exchanger, so that the apparatus can easily be carried indoors through a usual carrying entrance. In a refrigeration apparatus 1 including a high-temperature-side refrigerant circuit 25 and a low-temperature-side refrigerant-circuit 38, an evaporator 34 of the high-temperature-side refrigerant circuit 25 and a condensing pipe 42 of the low-temperature-side refrigerant circuit 25 constitute a cascade heat exchanger 43, and an evaporation pipe 62 of the low-temperature-side refrigerant circuit 38 is configured to cool a storage chamber 4 constituted in an insulating box body 2 to an extremely low temperature. The apparatus includes a mechanical chamber 3 which is constituted by the side of an insulating box body 2 and in which a compressor 10 and the like are installed, and an insulating structure 70 in which the periphery of the cascade heat exchanger 34 is surrounded with an insulating material is arranged in a side wall of the insulating box body 2 on the side of the mechanical chamber 3.
