PROBLEM TO BE SOLVED: To provide a novel composite brazing filler metal which has an excellent heat resistance and corrosion resistance and has good fluidity and brazing workability and a composite material for brazing and a brazed product. SOLUTION: This composite brazing filler metal consists of a laminate formed by superposing a titanium layer consisting of titanium or titanium alloy and a non-nickel layer consisting of copper, iron or their alloys. As a result, the excellent heat resistance and corrosion resistance can be exhibited as compared with the conventional brazing filler metals and therefore excellent bonding strength can be maintained and the better fluidity than that of the titanium alone can be obtained. In addition, handling is easier than that of the brazing filler metal in a powdery form and therefore the brazing workability is greatly improved.
