A graphite crucible for silicon single crystal manufacturing by the Czochralski method, having a long life cycle, contains at least one gas venting hole provided in a corner portion of the crucible. Gas generated by reaction between the graphite crucible and a quartz crucible is released to the outside through the gas venting hole, and formation of SiC on the surface of the graphite crucible and deformation of the quartz crucible caused by the pressure of the generated gas are prevented. |
