Method of continuously producing an acrylic resin sheet

Containing polymer, (1) and (2) satisfies the equation, the active energy ray-polymerizable viscous liquid 2 viscosity of 5000 mPa · s or more, between the endless belts 3 and the active energy ray transmissive film 5, or while the transfer sandwiched between the first and second active energy ray permeable film, and then cured by irradiation with active energy ray, continuously produce an acrylic resin sheet containing methyl methacrylate unit at least 50 wt% how to. (1) 30,000 ≦ Mw ≦ 500,000 (2) 35- (9 / 200,000) × Mw ≦ P ≦ 60 Mw is weight-average molecular weight of the polymer contained in the viscous liquid [-] P content ratio of the polymer contained in the viscous liquid [wt%]
