A crystal production method and a crystal production apparatus capable of improving the dissolution rate of a raw material in a solvent and stably maintaining a sufficient crystal growth rate. In a reaction vessel, (1) a supercritical and / or subcritical solvent, and (2) a crystal production method using a raw material to grow a crystal, the reaction vessel containing the raw material And the total of the maximum values of the internal horizontal cross-sectional areas of the raw material filling parts is 1.1 times or more of the internal horizontal cross-sectional area of the reaction vessel. And a crystal manufacturing apparatus used therefor. [Selection] Figure 1 |
