Provided is a cordierite-based sintered body having high specific stiffness. The cordierite-based sintered body contains cordierite as a primary crystal and alumina as an secondary crystal. Ca is contained at an amount of 0.2 to 0.8% by mass of the total mass in terms of CaO. The ratio (I Al /I mas ) of the peak intensity I Al of the main peak of alumina (2¸ = 35.0 - 35.5°) to the peak intensity I mas of the main peak of cordierite (2¸ = 28.0 - 29.0°) each measured with an X-ray diffraction device using a K±-ray of Cu falls within the range of 0.02 to 0.15. The cordierite-based sintered body substantially does not have a glass phase. |
