PROBLEM TO BE SOLVED: To provide a method of producing a raw material by which the formation of fine crystals emerging on growing of ZnO single crystals can be suppressed. SOLUTION: A slurried raw material 12 is produced by adding distilled water to ZnO powder, and slurrying the same. This slurried raw material 12 is stabilized at a low temperature (+60 deg.C) for 24 hr, and is thereafter fired at a high temperature (+1,000 deg.C) to produce a solid raw material 13. Then, the growing of ZnO single crystals 10 is performed by using the solid raw material 13, so that the formation of the fine crystals of ZnO caused by the liberation of the ZnO powder, and the subsequent floating thereof within a growing apparatus is suppressed.
