PROBLEM TO BE SOLVED: To provide zinc oxide powders having high ultraviolet-screening performance without damaging the applicability when used as cosmetics, coating materials and the like. SOLUTION: The zinc oxide powder comprises a platy particulate in which the primary particulates having the average particle size of ≥0.1 to ≤1 μm agglutinate in a plate-like form. The method for production of the zinc oxide powder comprising a platy particulate is characterized by: regulating the pH of the aqueous solution comprising zinc ions, chlorine ions and water to ≥5 to ≤6.5 to precipitate a zinc oxide precursor; hydrothermally treating the precursor-containing aqueous solution at a temperature of ≥170 to ≤250°C; lowering the temperature at a rate of ≥100 to ≤500°C/hr; and burning the dried hydrothermally-treated material at a temperature of ≥450 to ≤1,000°C.
