Patent abstract
The aluminum nitride sintered body includes at least europium, aluminum, and oxygen. It was found that a grain boundary phase having a peak having a X-ray diffraction profile substantially the same as that of an Sr3Al2O6 phase could be three-dimensionally continued in the aluminum nitride sintered body to realize a lower resistance without damaging various properties unique to aluminum nitride.
