An object of the present invention is to provide a methacrylic resin having high heat resistance, highly controlled birefringence, and excellent color tone and transparency. A methacrylic resin containing 5 to 40% by mass of a structural unit (B) derived from an N-substituted maleimide monomer in the main chain, and the structural unit (B) derived from an N-substituted maleimide monomer. In addition, the content of the component containing the structural unit represented by the formula (1), having a glass transition temperature of more than 120 ° C. and not more than 160 ° C. and having a light absorption at a wavelength of 400 nm in the methanol-soluble component is a single amount of N-phenylmaleimide A methacrylic resin and a production method thereof, a molded article, an optical component, or an automobile part, characterized by being 2% by mass or less in terms of body.
