Abstract: A resin molded product, a laminate, and a decorative sheet having high weatherability. A decorative sheet includes a resin molded product as a protective layer, and the resin molded product includes an ultraviolet absorber having pKa of ?5.5 or more and ?4.5 or less when irradiated with light, and a photostabilizer having pKa of 3.0 or more and 7.0 or less. The added amount of each of the ultraviolet absorber and the photostabilizer is 3.0 parts by mass or less per 100 parts by mass of the resin.
