The purpose of the present invention is to provide an oil-in-water emulsified sunblock cosmetic exhibiting an excellent feeling when used and capable of maintaining a high ultraviolet-ray protective effect even upon contact with water or sweat after application. The present invention pertains to an oil-in-water emulsified sunblock cosmetic containing an (A) ultraviolet-ray protective agent and a (B) fatty acid forming a solid at room temperature, the oil-in-water emulsified sunblock cosmetic being characterized in that 51% or less of the fatty acid is neutralized, and the formulation ratio ((A)/(B)) of the (A) ultraviolet-ray protective agent to the (B) fatty acid is in the range of at least 0.1 and less than 10.0. This cosmetic exhibits the unprecedented property of contact with water causing an improvement to the ultraviolet-ray protective ability thereof. It is preferable for the cosmetic to also contain an (C) oily component having an IOB of 0.5 or higher.
