PROBLEM TO BE SOLVED : To obtain a technology for growing crystal of BIG in which the amount of lead contained in BIG can be reduced to 0.1 wt.%, in the LPE method employing lead as a flux component. SOLUTION : When BIG is grown by LPE method using melt composed of a flux component containing a rare earth oxide and lead, mixture of lead into BIG can be suppressed by setting the Zn/Pb mol ratio of concentration in the melt at 0.15 or above.
