PROBLEM TO BE SOLVED: To provide a resin sheet for preparing a molded article shaped into a steric shape by hot plate molding that attains good dimensional accuracy of a printed design, generates no wrinkles on molding and have high designability. SOLUTION: The polycarbonate resin sheet for hot-plate molding is composed of a polycarbonate resin having a viscosity-average molecular weight of 21,500-25,000, has a heat shrinkage ratio in the extrusion direction and in the width direction of 0 to -5%, respectively, as measured at 180°C with a difference in the heat shrinkage ratio within 2% between portions adjacent to each other 100 mm apart in the extrusion direction and in the width direction, respectively, and has a plate thickness of 0.20-0.60 mm.
