A sunscreen cosmetic eliminates instability of a dibenzoylmethane derivative that is a UVA absorbing-agent, which exhibits excellent ultraviolet radiation protection performance across a wide wavelength region from UVA to UVB, and which exhibits excellent light resistance, is stable over time, and does not suffer from discoloration or crystal precipitation, and with which unnatural whiteness does not occur. A sunscreen cosmetic contains (a) a dibenzoylmethane derivative and (b) a powder that is surface-hydrophobized by means of treatment with a metal soap comprising a higher fatty acid and an alkaline earth metal or a combined treatment involving the use of a higher fatty acid and an alkaline earth metal hydroxide. The alkaline earth metal is preferably calcium or magnesium, and the higher fatty acid is preferably isostearic acid.
