Joined structures of metal terminals and ceramic members, joined structures of metal members and ceramic members, and adhesive materials

摘要

The object of the invention is to join a ceramic member and a metal member with a sufficiently high bonding strength and to prevent cracks in a ceramic material constituting the ceramic member. A joined structure of a metal terminal 8 and a ceramic member 1 has a joining layer 12 between the terminal 8 and the ceramic member 1. The joining layer 12 has a metal adhesive layer 6 containing at least metal indium. The invention further provides a joined structure of a metal member 8 and a ceramic member 1. The metal member has a tip face 8a and a side face 8b. A hollow 4 is formed in the ceramic member 1. A joining layer 12 is formed between a bottom surface 4a facing the hollow 4 and the tip face 8a of the member 8, and further formed between a side wall surface 4b facing the hollow 4 and the side face 8b of the member 8. The joining layer 12 has a metal adhesive layer 6 containing at least metal indium.
