Summary:A polycarbonate resin sheet which has a small heat shrinkage factor and small variations thereof and is useful for thermoforming and a production process therefor. The sheet is made of a polycarbonate resin and has a thickness of 0.2 to 2.0 mm, a heat shrinkage factor in the extrusion direction (MD) of 2 to 8% when it is heated at 180° C. for 10 minutes and a standard deviation of heat shrinkage factor in the transverse direction (TD) of 1.5 or less.
