PROBLEM TO BE SOLVED: To provide a coated fine particle having improved at least one of color, color development, gloss, light emission (fluorescence / phosphorescence), high luminance, light reflection and UV protection. The coated fine particles according to the present invention are obtained by rotating a vacuum vessel 1 having an internal cross-sectional shape of a polygon with a substantially perpendicular direction to the cross-section as a rotation axis. 3 is a coated fine particle in which the surface of the fine particle 3 is coated with an ultra fine particle or a thin film having a particle diameter smaller than that of the fine particle, and the ultra fine particle or the thin film is made of metal, It is composed of one selected from the group consisting of oxides, nitrides and carbides, or two or more composites selected from the above group, and can be used as cosmetics or paints.
