Abstract
A crucible for growing a single-crystal in which a raw material melt for growing the single-crystal is solidified while being accommodated includes a side wall part configured to surround the raw material melt and a bottom part configured to support the raw material melt while being continuous with the side wall part, in which the side wall part has circumferential length redundancy inside the side wall part in a cross-sectional view. The side wall part has a portion where the circumference length is redundant inside any portion in the cross-sectional view, and when the crucible for growing a single-crystal is cooled in a cooling process after the single-crystal growth, the portion where the circumference length is redundant inside in the cross-sectional view is expanded to an outside of the crucible for growing a single-crystal.
