Abstract

See full text

A joined body 20 includes a first member 21 which is a ceramic containing Si, a second member 22, and a joining portion 30 which is formed of an electrically conductive oxide containing a Fe3O4 phase and which joins the first member 21 and the second member 22. In the joined body 20, no reaction layer is preferably formed at a joining interface between the electrically conductive oxide and the first member 21. The joining portion 30 is preferably formed to have a multilayer structure in which from the first matter 21 to the second member 22, a first layer containing a first oxide of a transition metal, a second layer containing an electrically conductive oxide of a transition metal having a low valence as compared to that of the first oxide, and a mixed layer containing a transition metal and an oxide thereof are formed.
