PROBLEM TO BE SOLVED: To provide a supercritical cycle capable of easily mounting an inner heat exchanger by providing it between apparatuses and capable of reducing pipe length. SOLUTION: In this supercritical cycle, an evaporator 41, a compressor 33, a gas cooler 35 and a valve main body 39 of an expansion valve 37 are provided in this order. The inner heat exchanger 45 conducts heat exchange between a high pressure side refrigerant from the gas cooler 35 to the valve main body 39 of the expansion valve 37 and a low pressure side refrigerant from the evaporator 41 to the compressor 33. The expansion valve 37 is integrally equipped with a temperature sensing part 47 for controlling the valve main body 39 and has a bypass passage 51 for flowing the refrigerant from an upper stream side of the inner heat exchanger 45 where the high pressure side refrigerant flows to the temperature sensing part 47 and an orifice 53 for flowing the refrigerant from the temperature sensing part 47 to a refrigerant circuit on a downstream side of the valve main body 39.
