PROBLEM TO BE SOLVED: To improve degree of freedom of layout for storing an internal heat exchanger in an accumulator structuring a refrigeration cycle. SOLUTION: The internal heat exchanger 7 stored in the accumulator 6 structuring the refrigeration cycle 1 is structured by a cylinder shape member 17 with a tube shape member 16 stored in it and has a high pressure side refrigerant flow passage 9 extending to the tube shape member 16 along its longitudinal direction wherein its both ends are open and communicating with in-out ports 10, 11 and a lower pressure side refrigerant flow passage 12 extending between the tube shape member 16 and the cylinder shape member 17 along a longitudinal direction of the tube shape member 16 and the cylinder shape member 17 wherein its both ends are open and communicating with in-out ports 13, 14.
