PROBLEM TO BE SOLVED: To provide a sunscreen cosmetic which maintains a high ultraviolet ray-protecting effect in a UV-A region, reduces a sticky sense and a creaking sense, maintains an excellent sense of use, and is also excellent in water resistance. SOLUTION: The sunscreen cosmetic includes (A) a straight chain copolymerization type polyether-alkylene-methylpolysiloxane copolymer represented by general formula (1), (B) polymethylsilsesquioxane and (C) an ultraviolet absorber which exhibits a solid-like or paste-like state at 20°C and has the maximum absorption wavelength in a UV-A region. [In the formula, R is H or a 1 to 6C alkyl; (a) is an integer of 0 to 50; (b) is an integer of 0 to 50; (m) is an integer of 5 to 1,000; (n) is an integer of 2 to 100; (x<SB>1</SB>), (x<SB>2</SB>) are each an integer of 1 to 6, provided that (a)=(b)=0 does not hold].
