1. A Cr—Si-based sintered body, consisting of: a sintered body comprising chromium and silicon and having a crystal structure, wherein the crystal structure attributed by X-ray diffraction includes CrSi2 and silicon such that a CrSi2 phase is present at 60.1 wt % to 97.6 wt % in a bulk, a density of the sintered body is from 96.6% to 99.9%, an average grain size of the CrSi2 phase is from 3 um to 10 um, and the sintered body includes inevitable metal impurities other than chromium and silicon such that an amount of the inevitable metal impurities is 1 wt % or less in the bulk, and the sintered body has an oxygen amount of 0.02 wt % or less in the bulk, wherein the sintered body has a flexural strength of from 185 M Pa to 321 M Pa.
