PROBLEM TO BE SOLVED: To secure a melting point and a brazing property while reducing a weight ratio of Au in a brazing filler of an Au-Ag-Sn alloy. SOLUTION: Composition ratio of [Au (wt%), Ag (wt%), Sn (wt%)] of the brazing filler is in an area surrounded by a line which connects 6 points of point 1 (53.0, 23.5, 23.5), point 2 (65.9, 12.3, 21.8), point 3 (66.1, 15.0, 18.9), point 4 (67.3, 19.1, 13.6), point 5 (45.5, 39.0, 15.5), point 6 (49.6, 28.7, 21.7) and the balance thereof is an unavoidable component.
