PROBLEM TO BE SOLVED: To improve the quality of a grown crystal. ! SOLUTION: A method of manufacturing a crystal includes: a preparation process of preparing a seed crystal 3, a solution 6, a crucible 5, and a heating device 11; a crystal first growth process of growing a crystal 2 on an underside surface of the seed crystal 3; a granular crystal formation process of forming a granular crystal 7 in the crucible 6 by making a temperature gradient in the solution 6 large by heating a part of the crucible 5 by the heating device 11 so that the temperature of the part of the crucible 5 becomes higher than temperatures of other parts after the crystal 2 is grown; a crystal second growth process of growing the crystal 2 so that a part of the granular crystal 7 positioned in the crystal 2 projects from the underside surface of the crystal 2 by sticking the granular crystal 7 on the underside surface of the grown crystal 2 and further growing the crystal 2; and a separation process of separating the crystal 2 hav |
