PROBLEM TO BE SOLVED: To provide an apparatus for supplying a molten raw material which can continuously supply the molten raw material little by little while preventing solidification of the molten raw material even at a comparatively low temperature, at which the liquid temperature of the molten raw material is close to the melting point of the raw material, without installing a special heating means, in supplying the melt raw material into a main crucible of an apparatus for manufacturing a polycrystal substance or single-crystal substance. SOLUTION: In the apparatus 1 for supplying the molten raw material including a sub-crucible 2 having a melting vessel, a heating means 8 installed around the sub-crucible 2, and a raw material supply means 9 for supplying a solid raw material to the melting vessel of the sub-crucible 2, a void part 3 is formed between the melting vessel of the sub-crucible 2 and the heating means 8, and a molten raw material 5 overflowed from the melting vessel is supplied to the main crucible of the apparatus for manufacturing a polycrystal substance or single-crystal substance through the void part 3.
