Abstract
An aluminum nitride sintered body is characterized by having a g-value of an unpaired electron in a spectrum of an electron spin resonance being not less than 2.0010. The aluminum nitride sintered body is produced by sintering a raw material composed of powdery aluminum nitride at a temperature of not less than 1730.degree. C. to not more than 1920.degree. under a pressure of not less than 80 kg/cm.sup.2.
