Abstract
A joined bodyincludes a first memberhaving a thermal expansion coefficient of 8 ppm/K or less, a second memberhaving a thermal expansion coefficient of 12 ppm/K or more, and a joining portioncomposed of an electrically conductive oxide containing 50% by mass or more of a spinel-type ferrite phase, the joining portionjoining the first member and the second member. The electrically conductive oxide preferably contains Fe and element A (where element A represents one or more selected from the group consisting of Mg, Mn, Co, Ni, Cu, and Zn). The molar ratio of element A to Fe, i.e., A/Fe, is 0.5 or less.
