The black brightening flake comprises a metal oxide, as a mother material, which is derived from a colloidal metal oxide particle and 5 to 70% by mass black pigment dispersedly contained in the base material. The black brightening flake has an average particle diameter of 3 to 500 mum, an average thickness of 0.1 to 5 mum, and an average aspect ratio of 5 to 300.
