摘要：
A ceramic substrate and a metallic layer formed thereon are bonded closely by means of a bonding layer formed between the ceramic substrate and the metallic layer. The ceramic substrate comprises either alumina or a ceramic containing alumina, and the metallic layer comprises either molybdenum (Mo) or an alloy composed of molybdenum (Mo) and at least one of titanium (Ti), zirconium (Zr) and niobium (Nb). The bonding layer comprises composite oxides of aluminum and at least one of titanium (Ti), zirconium (Zr) and niobium (Nb) and formed by either a process of (1) forming an intermediate layer comprising at least one of titanium (Ti), zirconium (Zr) and niobium (Nb) between the ceramic substrate and the metallic layer, and subjecting the laminated substance to a heat treatment to a cause a reaction between alumina and the intermediate layer; or (2) forming an alloy layer comprising an alloy of molybdenum (Mo) and at least one of titanium (Ti), zirconium (Zr) and niobium (Nb) directly on the ceramic substrate, and subjecting the laminated substance to a heat treatment to cause a reaction between alumina and at least one of titanium (Ti), zirconium (Zr) and niobium (Nb) contained in the alloy layer.
