An objective of the present invention is to provide a method for producing an extruded resin sheet in which the extruded resin sheet unlikely to be broken. The present invention provides a method for producing an extruded resin sheet comprising: heat-melting a thermoplastic resin and then extruding it into a sheet-form through a die; and pressure-forming the extruded molten thermoplastic resin sheet while nipping it with a first roll and a second roll; wherein at the both side edge portions of the outer circumferential surface of the second roll, the level difference portions which have a diameter smaller than a diameter of the roll central portion are provided, and the both side edge portions of the extruded molten thermoplastic resin sheet are nipped with the first roll and the level difference portions of the second roll. |
