A decorative sheet (S) for in-mold decorating injection molding has a base sheet (1A) and a resin layer (2) formed on a surface of the base sheet (1A) to be brought into contact with an injection-molded molding and containing an acrylic-modified polyolefin resin. The acrylic-modified polyolefin resin is a resin composed by grafting-copolymerizing an acrylic monomer and/or an acrylic prepolymer on principal chains of a polypropylene resin. The decorative sheet (S) includes, for example, a base sheet (1A) of an acrylic resin, a decorative layer (3) of a binder resin and at least either an acrylic resin contained in the binder resin or a polyvinyl chloride-acetate resin, and a bonding layer (2) containing an acrylic-modified polyolefin resin. A primer layer (4) may be sandwiched between the bonding layer (2) and the decorative layer (3).
