When at least one selected from the group consisting of n and Ti is contained, effects such as lowering of melting point of brazing material, improvement of wettability, acceleration of age hardening and the like can be obtained, and joint strength can be improved. Further, by forming the metal layer containing Al as a main component on the surface of the ceramic member, the wetting property between the surface of the ceramic member and the brazing material is improved, and the bonding strength with the aluminum member can be increased. Further, by forming a plurality of layers with the metal layer containing Al as the main component being the uppermost layer on the surface of the ceramic member, the wetting property between the surface of the ceramic member and the brazing material is improved and the bonding strength with the aluminum member is improved. Can be increased. Further, when the thickness of the “metal layer containing Al as a main component” is thinner than 0.08 μm, the bonding strength is low, but when it is 0.08 μm or more, a high-strength bonded body can be obtained. It is because the metal layer containing Al as a main component increases the wetting property between the surface of the ceramic member and the brazing material at the time of joining. However, it is not preferable to extremely thicken the metal layer containing Al as a main component, which exceeds 5 μm, because it increases the manufacturing cost of the bonded body. Further, even if the metal layer containing Al as a main component alone has a high adhesion strength to the ceramic member,
The adhesion strength between the ceramic member and the metal layer containing Al as a main component is improved by interposing one or more intermediate metal layers having good reactivity with the ceramic member between the metal layer containing Al as a main component and the ceramic member. As a result, the joint strength is increased. For example, Ti layer, Zr layer, Mo
It is preferable to interpose one or more as an intermediate metal layer such as + Mn layer.

Join using. As the aluminum member 2, various aluminum member casting materials specified by JIS were used. On the surface of each ceramic member 1, a plurality of layers 4 in which the metal layer 40 containing Al as a main component is the uppermost layer are formed in advance. Specifically, as shown in Table 2, after forming the intermediate metal layer 41 on the surface of the ceramic member 1 by the formation method shown in Table 2, the uppermost metal layer 40 is formed. Separately, the brazing filler metal 3 was melted with the composition shown in Table 2 and poured on a rotating water cooling roll made of Cu (liquid quenching method) to form a foil (diameter 18 mm, thickness 1
00 μm) was prepared.

The bonded body was obtained by holding it for 0 minutes to carry out bonding. After joining
According to JIS No. 4, a tensile test piece was subjected to a finishing test. Table 2 shows the results. As shown in Table 2, the bonded body obtained by the manufacturing method of the present invention had high bonding strength. Specifically, the aluminum member 2 at the joint interface was deformed first, and then the interface between the aluminum member 2 and the ceramic member 1 was fractured. The fracture surface has a shape in which the aluminum member 2 is attached to the fracture surface of the ceramic member 1. The joint strength of the brazing material was equivalent to that of the aluminum member 2 or the ceramic member 1 itself. On the other hand, in the joined body produced by the manufacturing method of the comparative example, the joining strength was low because it was not joined or was the starting point and the progress of fracture was in the joined interface or in the brazing filler metal 3 layers.
