Abstract: An expanded polypropylene resin bead contains an inorganic pigment, a hindered amine compound, and an ultraviolet light absorber. The ultraviolet light absorber contains an ultraviolet light absorber A having a molecular weight of 360 or more, and a content of the ultraviolet light absorber A in the expanded polypropylene resin bead is 0.010% by mass or more and 2% by mass or less. An expanded polypropylene resin beads molded article is produced by in-mold molding of the expanded polypropylene resin bead.
