PROBLEM TO BE SOLVED: To provide a brazing filler metal with less voids and having the high joining strength even when the brazing filler metal is exposed to not only the room temperature but also to high temperature, and a joined body which is joined by using the same.SOLUTION: The brazing filler metal includes a member to be joined which consists of a ceramic sintered body. The brazing filler metal is used for joining a plurality of members to be joined with each other. The brazing filler metal contains no copper, but metal components of at least one kind of reactive metal of silver, titanium, zirconium, hafnium, and niobium, and cobalt. The content of each metal component, by mass, to the total 100% is ≥90% for silver, ≥0.5% and ≤9.0% for reactive metal, ≥0.3% and ≤5.0% for cobalt. |
