A polymethacrylate composition of the present invention includes polymethacrylate, an antioxidant containing a first compound represented by Formula (I) and a second compound represented by Formula (II). The polymethacrylate has a weight average molecular weight of 50,000-150,000, and includes 92-99 wt% of a methacrylate monomer unit and 1-8 wt% of an acrylate monomer unit. The amount of the antioxidant is equal to or greater than 0.005 to less than 0.3 parts by weight based on 100 parts by weight of the polymethacrylate. |
