PROBLEM TO BE SOLVED: To provide a new composite brazing filler metal which has excellent heat resistance and corrosion resistance, and has satisfactory brazing operability and excellent joining strength, to provide a composite material for brazing, and to provide a brazed product. SOLUTION: The composite brazing filler metal consists of a stacked body obtained by stacking a nickel layer consisting of nickel or a nickel alloy, and a non-nickel layer consisting of titanium, manganese, tin, zinc, aluminum, copper or their alloys. Thus, the composite brazing filler metal can exhibit excellent heat resistance and corrosion resistance, can therefore maintain excellent joining strength, and further, has satisfactory fluidity compared with a nickel simple substance, and is made easy to be treated compared with the powdery one, so that its brazing operability remarkably improves.
