PROBLEM TO BE SOLVED: To provide an acrylic block copolymer composition which is excellent in weather resistance (light fastness), thermal melting property and transparency, and a molded article formed by molding the composition. SOLUTION: This thermoplastic elastomer composition is characterized by comprising (a) a methacrylic polymer block and (b) an acrylic polymer block and containing (A) an acrylic block copolymer having an acid anhydride group and/or a carboxyl group, (B) an acrylic polymer having 1.1 or more of (C) reactive functional groups relative to one molecule, and (D) cerium oxide particles in at least one polymer block of the methacrylic polymer block (a) and acrylic polymer block (b).
