Abstract
. Thus, there are provided a quartz glass crucible for pulling a silicon single crystal, the quartz glass crucible being increased in mechanical strength, making it possible to suppress deformation of a quartz glass crucible for pulling a silicon single crystal during a single crystal pulling process, thereby prevent degradation in yield rate due to dislocation in a single crystal and make the manufacture of a silicon single crystal highly efficient and a method of manufacturing the same quartz glass crucible.
