Zusammenfassung:	PROBLEM TO BE SOLVED: To provide coated powder and a cosmetic which exhibit excellent protection against ultra violet rays in UV-A and UV-B regions. SOLUTION: A thin flake substrate is coated with iron-doped titanium dioxide to produce powder and then the powder is mixed in a cosmetic. The iron-doped titanium dioxide to be coated on the thin flake substrate may be further doped with at least one element selected from the group of aluminum, silicone, titanium, zirconium, tin and antimony or be coated with an oxide hydrate or an oxide thereof. The thin flake substrate is preferably selected from sericite, talc, mica and kaolin.
