摘要： PROBLEM TO BE SOLVED: To provide a metallic material for brazing having excellent corrosion resistance and brazing property, and to provide a brazing method and a heat exchanger. SOLUTION: The brazing method is provided for brazing a metallic material 1 for brazing to another metallic material 2. The metallic material for brazing includes a base material portion 10 made of copper or a copper alloy containing chrome 11 by a predetermined amount, and a metallic film portion 20 made of a material having a melting point lower than a heating temperature in brazing, and provided on the surface of the base material portion 10. The brazing method includes: an assembling step of assembling the metallic material 1 for brazing and the another metallic material 2 in a predetermined positional relationship to form an assembly; a brazing step of heating and brazing the assembly, in which the metallic film portion 20 is melted to diffuse chrome 11 into a surface of the metallic material 1 for brazing by performing brazing and heating in an oxidation inhibition atmosphere; and a film forming step of forming a chrome oxide film 30 by using the chrome 11 diffused into the surface of the metallic material 1 for brazing in atmosphere after the brazing step.
