Claim 0:
1. A methacrylic resin having a structural unit (X),
the structural unit (X) comprising a cyclic structure in a main chain thereof,
the methacrylic resin having a glass transition temperature (Tg) of higher than 120° C. and 160° C. or lower,
an emission intensity at a wavelength of 514 nm in terms of a concentration of a solution of fluorescein in ethanol being 30×10−10 mol/L or less when a solution containing 2.0 mass % of the methacrylic resin in chloroform is spectroscopically analyzed using an excitation wavelength of 436 nm and a slit width of 2 nm.
