Abstract:
The ceramic-metal bonding structure in accordance with the present invention includes: a ceramic member of an oxide ceramic; a metallic member which is mainly made of Fe and contains Ni and includes an end; an adhesive layer formed on the ceramic member; and a brazing material. The brazing material bonds the adhesive layer and the end of the metallic member. The adhesive layer contains an active metal capable of reacting with the oxide ceramic and has a thickness of equal to or less than 1.5 μm. An intermetallic compound of the active metal and the Ni exists inside the brazing material so as to be between the adhesive layer and the end of the metallic member.
