A bonding agent for metals or ceramics comprising 0.25 to 18.0% by weight of a powder of Mg and 25 to 50% by weight of a hydroxyl solvent, the balance of its composition being a powder of AlN. The bonding agent having the constituents stated above has a large amount of reaction heat generated by the reaction of its constituents. This reaction heat destroys thermally any strong oxide film existing on the surface of a base body or a part to be joined thereto, and forming a barrier layer hindering their bonding when the base body and the part to be joined thereto are of an aluminum alloy. <IMAGE> |
