Zusammenfassung:	In order to provide a method of manufacturing an aluminum flake pigment having a small mean particle size as well as high brightness, a method of manufacturing an aluminum flake pigment including a step of flaking aluminum powder in an organic solvent with a grinder having grinding media, which grinding media contain steel ball grinding media formed by spherical media consisting of a material including steel and having diameters in the range of 0.3 mm to 1.0 mm, is provided. The mean particle size (D50Al) of this aluminum powder is preferably in the range of 1.0 to 10.0 μm. Further, this grinder is preferably a ball mill.
