Zusammenfassung:PROBLEM TO BE SOLVED: To provide a methacrylic resin composition having excellent moldability and impact resistance, and a molded article.SOLUTION: The methacrylic resin composition includes: (A) 2-98 pts.mass of multilayer polymer particles comprising an inner layer containing a crosslinked elastomeric polymer (I) mainly having a unit derived from an alkyl acrylate containing at least a 1-8C alkyl group and/or a unit derived from a conjugated diene and an outermost layer containing a thermoplastic polymer (II) composed of a unit derived from an alkyl methacrylate mainly containing a 1-8C alkyl group, (B) 98-2 pts.mass of a thermoplastic polymer composed of ≥80 mass% of a methyl methacrylate unit and ≤20 mass% of a vinyl-based monomer unit (the total of components (A) and (B) is 100 pts.mass), (C) 0.01-0.2 pt.mass of a hindered amine, (D) 0.05-0.5 pt.mass of a hindered phenol-based antioxidant and (E) 0.01-0.2 pt.mass of a fatty acid metal salt.
