PROBLEM TO BE SOLVED: To provide a method for growing a single crystal not cracking. SOLUTION: In this method for growing a single crystal by heating a raw material in a crucible to give a melt and growing the single crystal while pulling up a seed crystal, a large-sized crucible composition >=ϕ120mm crucible diameter is used. After the crucible diameter reaches >= about 30% the inner diameter of the crucible, a condition in which the solid-liquid interface shape is reversed from a protruded state to the melt side to a flat state or a protruded state to the crystal side is set to give the single crystal.
