PROBLEM TO BE SOLVED: To provide: a solid raw material supply device that is capable of not only suppressing any splashing when an aggregated solid raw material is supplied into a crucible but also suppressing the scattering of any splash having occurred; a molten raw material supply device that includes the solid raw material supply device; and a crystal production apparatus. SOLUTION: The solid raw material supply device 10 comprises: a guide member 1 for guide and supply of the aggregated solid raw material 4 to an opening of a sub-crucible 21; a solid raw material supply unit 3 for supply of the solid raw material 4 to the guide member 1; and a scattering preventive member 2. Further, there are provided the molten raw material supply device 20 including the solid raw material supply device 10, and the crystal production apparatus 100. COPYRIGHT: (C)2008,JPO&INPIT
