ABSTRACT:
A bonded member including a ceramic base material1and a metallic member7which are bonded together, wherein a solder material5comprising Au is disposed on the surface of the ceramic base material1via an active metal layer, the active metal layer and the solder material5are molten by heating so as to form a precoat layer6, the metallic member7is disposed on the surface of the precoat layer6via an insertion metal layer comprising pure metal which may form an alloy having a lower melting point than Au with Au or an alloy of the pure metal and Au, and the insertion metal layer and at least a portion in the vicinity of the interface between the insertion metal layer and the precoat layer6are molten by heating to bond the metallic member7and the precoat layer6.
