Zusammenfassung:PROBLEM TO BE SOLVED: To provide a thermoplastic resin composition having scratch resistance, excellent in weather resistance, scratch resistance, color development, and shock resistance and heat resistance, and to provide its molded article.SOLUTION: There are provided a composition containing 10 pts.mass or more and less than 30 pts.mass of a graft polymer (B) obtained by graft polymerization of a specific monomer mixture (m1) to a crosslinked ethylene and α-olefin copolymer (A) crosslinking treated so that the gel content is 50 to 85 mass%, 10 to 80 pts.mass of a methacrylic ester resin (C) having specific glass transition temperature obtained by polymerization of monomer mixture (m2) containing N-substituted maleimide or maleic acid anhydride, aromatic vinyl and methacrylic acid ester to the crosslinked ethylene and α-olefin copolymer (A), and 10 to 80 pts.mass of a methacrylate ester resin (D) obtained by polymerization of monomer components (m3) containing methyl methacrylate of 95 mass% or more to the crosslinked ethylene and α-olefin copolymer (A) (excluding the methacrylic acid ester resin (C)) (where, (B)+(C)+(D)=100 pts.mass), and a molded article.
