<P>PROBLEM TO BE SOLVED: To secure the melting point and the brazability of a brazing filler metal of Au-Ag-Cu alloy, while decreasing the weight ratio of Au constituting the brazing filler metal. Ž<P>SOLUTION: The brazing filler metal has a composition ratio äAu(wt.%), Ag(wt.%), Cu(wt.%)} existing within the region enclosed by straight lines connecting 8 points, which are a point 1 (42, 33, 25), a point 2 (38, 34, 28), a point 3 (21, 47, 32), a point 4 (10, 59, 31), a point 5 (9, 63, 28), a point 6 (20, 57, 23), a point 7 (31, 47, 22), and a point 8 (42, 35, 23), in a ternary composition diagram of Au, Ag, and Cu, and has the balance consisting of inevitable elements.
