PROBLEM TO BE SOLVED : To provide a growing method for a garnet-type single crystal whereby a large-sized grown crystal is yielded, the orientation control of the crystal is made possible, and the compositional difference in the crystal is not caused. SOLUTION : In this growing method, a seed crystal is brought into contact with a melt which at least crystallizes X3Fe5O12 [wherein X is Y (yttrium), (Bi, Re (provided Re is a rare earth element)), or (Bi Tb)]; then, while an X3Fe5O12 single crystal is being grown by drawing up the seed crystal, a raw material having the same weight and composition as that of the above drawn-up single crystal is supplied to the melt.
