PURPOSE:To provide a ceramics-metal joining body satisfying sufficient high joining strength and high reliability for a cooling-heating cycle or the like. CONSTITUTION:The ceramics-metal joining body is obtained by joining a metal member to a nitride based ceramic member through a Ag-Cu brazing filler metal layer containing at least one kind of an active metal selected among Ti, Zr, Hf and Nb. A compound, mainly nitride particles which are the reaction product of the active metal in the brazing filler metal with the nitride based ceramic member are present in layers in the joining boundary of the nitride based ceramic member side. The compound particles containing the active metal are spherical particulates large in stress relaxation effect and <=100nm in diameter.
