PROBLEM TO BE SOLVED: To provide a heat exchanger capable of effectively effecting heat exchange between the high-pressure side and the low-pressure side of a refrigerant. SOLUTION: The heat exchanger 7, employed for a compression-type refrigerating cycle, in which the refrigerant is circulated to effect heat exchange between the high-pressure side and the low-pressure side of the refrigerant, is equipped with a tubular body 710 for conducting the high-pressure side and the low-pressure side of refrigerant to flow therethrough, to effect the heat exchange by heat transferred to a tubular body and the tubular body is equipped with a first flow passage layer 711, consisting of high-pressure side refrigerant flow passages 7a installed in a row, and a second flow passage layer consisting of low-pressure side refrigerant flow passages 712a installed in a row, while the tubular body is provided with the inlet port section 720 and the outlet port section 730 of the first flow passage layer, as well as the inlet port section 740 and the outlet port section 750 of the second flow passage layer. |
