The present invention provides a powder that can display excellent protection ability in both UV-A and UV-B regions. The titanium oxide-zinc oxide aggregate powder comprises an aggregate formed by the aggregation of porous titanium oxide particles and zinc oxide particles, and said porous titanium oxide particle is an aggregate of primary fine particles of titanium oxide. The production method of the titanium oxide-zinc oxide aggregate powder comprises the steps of: (a) hydrolyzing, with heating, an aqueous solution containing a titanium salt and an aliphatic alcohol; (b) adding a water-soluble zinc salt to a suspension of a precipitate obtained by the hydrolysis with heating in step (a), and then neutralizing the suspension with an alkali; and (c) calcining a precipitate obtained by the neutralization in step (b).
