A method for producing a thermoplastic resin sheet, by extruding a molten thermoplastic resin like a sheet from a die, and cooling and solidifying the sheet on a cooling drum according to the electrostatic charging method, comprising the use of a conductive tape, (A) the section of which is formed almost like a rectangle with a thickness of X (mm) and a width of Y (mm) satisfying the following formulae (1) to (3) <MATH> <MATH> <MATH> <MATH> (B) with a thickness variation Z of less than 30% in the longitudinal direction as a charging electrode for casting. The method allows the production of a thermoplastic resin sheet excellent in thickness uniformity with few surface defects at a high speed of 65 m/min or higher, particularly 100 m/min or higher, more particularly 150 m/min or higher. <IMAGE> |
