PROBLEM TO BE SOLVED: To provide a crystal manufacturing apparatus that can continuously, inexpensively and easily manufacture single crystals or polycrystals with high qualities. SOLUTION: A crucible body 14 containing a source material is placed in a heating furnace 11 and kept at the temperature of the melting point of the source material or higher while oxidation is prevented in an inert gas atmosphere; a source material melt 25 is made to flow downward through a hole 17 formed in the bottom of the crucible body 14 to a reservoir container 30 mounted on a lifting table 31 in a liquid receiving room 23 disposed below the crucible 14; then the reservoir container 30 is descended with the lifting table 31; the reservoir container 30 is transferred from the lifting table 31 to a plurality of solidifying rooms 41 placed adjacent to the liquid receiving room 23; the source material is cooled for a predetermined time in the solidifying room 41; the material is further cooled to normal temperature in a cooling room placed adjacent to each solidifying room 41; and the solidified ingot is taken out from the cooling room.
