    摘要: The present invention provides a methacrylic resin composition comprising
    100 parts by mass of a methacrylic resin comprising 50 to 97% by mass of a methacrylic acid ester monomer unit (A), 3 to 30% by mass of a structural unit (B) having a ring structure in the backbone, and 0 to 20% by mass of an additional vinyl monomer unit (C) copolymerizable with a methacrylic acid ester monomer, and
    0.001 to 0.2 parts by mass of a compound (D) having a predetermined structure,
    the methacrylic resin composition satisfying the following conditions (I) and (II):
    (I): a weight-average molecular weight of the methacrylic resin composition as measured by gel permeation chromatography (GPC) is 65,000 to 300,000, and
    (II): a mass ratio between the component (D) and the structural unit (B) having a ring structure in the backbone is 25 ≤ (B)/(D) ≤ 1000.
