PROBLEM TO BE SOLVED: To provide the fixing structure of a refrigerant pipeline, which realizes simplification of mounting work of a heat transfer tube to a stay. SOLUTION: In a fixing structure, wherein a heat transfer tube 4 is fixed to the side surface of a stay 1 via a pipe holder 20, the stay 1 and the pipe holder 20 are formed integrally of a resin material. According to this constitution, when compared with a case where the heat transfer tube is supported by the combination of a stay made of SUS and an elastic retention type pipe holder, fixed by fitting the same into a holder receiving hole provided on the stay, for example, since the fitting work of the pipe holder into the holder receiving hole is not necessary, the forming work of the holder receiving hole on the stay is not necessary whereby the fixing work of the heat transfer tube 4 to the stay 1 is very much simplified, and working cost can be reduced. As a result, the substantial reduction in the manufacturing cost of a heat exchanger equipped with such a fixing structure of refrigerant pipeline, can be realized.
