PROBLEM TO BE SOLVED: To provide a refrigeration cycle device using a non-azeotropic refrigerant capable of achieving sufficient heat exchange quantity by a first cooler in a composition separation circuit, and capable of simplifying a refrigerant circuit. SOLUTION: This device is provided with a refrigerant cycle part 10 constituted by connecting a compressor 1, a condenser 2, a first decompressor 3 and an evaporator 4 by piping in order; and a composition separation circuit part 20 wherein a composition separation means 11 for separating the non-azeotropic refrigerant into a low boiling point refrigerant component and a high boiling point refrigerant component, the first cooler 12 using the waste heat of the evaporator 4 arranged on an upper part of the composition separation means 11 as a heat source and a refrigerant reservoir 13 are connected annularly. The refrigerant cycle part 10 and the composition separation circuit part 20 are connected by a first pipe 41 and a second pipe 42, an end of the first pipe 41 is connected to a lower part of the composition separation means 11, the other end is connected to a pipe between a delivery part of the compressor 1 and the condenser 2, an end of the second pipe 42 is connected to the lower part of the composition separation means 11, and the other end is connected to a pipe between the first decompressor 3 and a suction part of the compressor 1 through a second decompressor 31.
