A carbon-containing aluminum nitride sintered compact comprising an aluminum nitride matrix and, incorporated therein, a carbon which has peaks appearing in the vicinity of 1580 cm-1 and 1355 cm-1 as measured by the laser Raman spectrometry. The carbon-containing aluminum nitride sintered compact does not suffer from a short circuit due to its satisfactorily high volume resistivity of at least 1 x 108 Φ • cm in a high temperature region of 200 °C or higher (for example, 500 °C or so), is excellent in hiding properties, is increased with respect to radiant heat and can secure high accuracy in the measurement by a surface thermometer. |
