摘要

A heat exchanger 10 includes a brazing heat exchanging tube S and a fin 4. The heat exchanging tube S and the fin 4 are brazed with each other via the brazing layer 11 of the heat exchanging tube S. The brazing layer 11 is formed by spraying of a brazing material consisting of Si: 6 to 15 mass%, Zn :1 to 20 mass%, at least one of Cu: 0.3 to 0.6 mass% and Mn: 0.3 to 1. 5 mass, and the balance being aluminum and inevitable impurities.
