Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for producing a resin plate with reduced strain without reducing productivity. SOLUTION: In the method for producing an acrylic resin plate by casting a polymerizable raw material into a casting mold, and polymerizing and curing the polymerizable raw material, the viscosity of the polymerizable raw material is controlled according to the thickness of the acrylic resin plate in such a manner that (1) when the thickness is less than 8 mm, the viscosity is 0.12-0.36 Pas; (2) when the thickness is not less than 8 mm to less than 40 mm, the viscosity is 0.18-0.42 Pas; and (3) when the thickness is not less than 40 mm, the viscosity is 0.48-0.72 Pas.
