The present invention provides a process for continuously producing a polymer sheet having an excellent surface smoothness, an apparatus for producing such a polymer sheet, and an optical polymer sheet produced by such a process. The process for producing a polymer sheet comprises coating or laminating, on a polymer base sheet, an ultraviolet-curing resin composition, adhering the coated or laminated polymer base sheet to a member having a smooth surface whose maximum surface roughness (Rmax) satisfies Rmax&lE;0.1 &mgr;m, in a state that the ultraviolet-curing resin composition is soft, and applying an ultraviolet light to transfer smoothness of the smooth surface of the member onto the polymer base sheet.
