PROBLEM TO BE SOLVED: To provide an Al alloy-ceramics composite material joined body which has satisfactory air-tightness so as to prevent the leak of gas, and in which the joint has high strength. SOLUTION: Disclosed is a joined body obtained by joining Al alloy-ceramics composite materials using an Al alloy having an Mg content of <0.5 mass% as a matrix via a joining layer using a joining material having a composition comprising Al, Zn, Mg and the other impurity components, and in which the mass ratio between Al and Zn, Al/Zn is 0.85 to 2.33 and the Mg content is 0.5 to 5.0 mass%, and comprises a diffusion layer where Zn in the joining material is diffused into the Al alloy in the matrix of the Al alloy-ceramics composite materials in contact with the joining layer.
