PROBLEM TO BE SOLVED: To provide a method for producing a thermoplastic resin sheet in which in a static electricity applying cast method using tape electrodes, the generation of the defect of electricity application nonuniformity in the sheet is prevented stably for a long time. SOLUTION: In the method for producing the sheet, when a thermoplastic resin is extruded from a nozzle into a sheet, and the sheet is made to adhere to a cooling drum by the static electricity applying cast method, cooled, and solidified for molding, an electrostatic charge is applied to the sheet by using the tape electrodes which have a rectangular cross section of a uniform form in the longitudinal direction and are made of stainless steel containing at least 10 wt.% of nickel.
