PROBLEM TO BE SOLVED: To maintain a bonded state of a bonded body for a long period of time even in the case of exposing a brazing material layer to an oxidizing atmosphere in a high-vacuum atmosphere at a high temperature in obtaining the bonded body by bonding a ceramic member to a metal member with the metal brazing material layer. SOLUTION: A brazing material containing 50-99 wt.% of copper, 0.5-20 wt.% of aluminum and 0.5-5 wt.% of one or more active metals selected from the group consisting of titanium, zirconium, hafnium, vanadium and niobium is used. A ceramic member 6 is brazed to another member 3 to give a bonded body provided with the ceramic member 6, the other member 3 and a brazing material layer. The brazing material layer is heated in an oxidizing atmosphere at a temperature preferably lower than the solidus line of the brazing material. |
