The present invention is intended to enhance mechanical property and improve complex and fine processability for a cordierite-based sintered body without compromising low thermal expansibility, high dimensional long-term stability, high stiffness (high elastic modulus) and precision polishing characteristic. The cordierite-based sintered body of the present invention comprises cordierite as a primary crystal phase and LaMgAl 11 O 19 as a secondary crystal phase, wherein a ratio I LMA (114) / I MAS (004) is in the range of 0.01 to 0.8, where the I LMA (114) denotes a peak intensity of a (114) plane of LaMgAl 11 O 19 as measured by powder X-ray diffractometry, and the I MAS (004) denotes a peak intensity of a (004) plane of cordierite as measured by powder X-ray diffractometry.
