摘要

A joined structure includes a metal terminal, a ceramic member and a joining layer between the metal terminal and the ceramic member. The joining layer includes a metal adhesive layer containing at least indium metal. The invention further provides a joined structure including a metal member, a ceramic member, and a joining layer. The metal member includes a tip face and a side face. A hollow portion is formed in the ceramic member. The joining layer is formed between a bottom surface facing the hollow portion and the tip face of member, and further formed between a side wall surface facing the hollow portion and the side face of the metal member. The joining layer also includes a metal adhesive layer containing at least indium metal.
