Abstract

PURPOSE: To provide a seed crystal holder capable of fixing a tapered seed crystal so that it is not moved during pulling by fixing the crystal using a support rod having a seed crystal holding groove tapered in the pulling axis direction.
CONSTITUTION: In order to insert seed (seed crystal) 3 into holder (support rod) 1, side hole 10 and/or a central through hole is made in rod 1. Through hole 12 is made in seed 3 at the upper tapered part. Seed 3 is then inserted into rod 1 from seed insert inlet side 10 or the central through hole, and it is put into a tapered groove under the hole. At this state, wire 13 is passed through hole 12, and seed 3 is fixed into rod 1 firmly and surely with screws 14, 15.
