Abstract:
A conductive sintered oxide which includes: a conductive crystal phase having a perovskite structure represented by (RE1-cSrc)MdO3, in which RE is a group of elements consisting of Yb and/or Lu and at least one element selected from Group IIIA elements excluding Yb, Lu and La, and M is a group of elements consisting of Al and at least one element selected from Groups IVA, VA, VIA, VIIA and VIII, a first insulating crystal phase represented by RE2O3, and a second insulating crystal phase represented by SrAl2O4. The conductive crystal phase has a coefficient c satisfying 0.18
