PROBLEM TO BE SOLVED: To provide a resin composition which is excellent in transparency, hardly suffers from deformation by moisture absorption and has an excellent surface hardness. SOLUTION: The resin composition (D) comprises a methacrylic polymer (A) comprising at least 50 mass% of a methyl methacrylate unit, a crosslinked methacrylic polymer particle (B) comprising 50-99.7 mass% of the methyl methacrylate unit, 0-49.7 mass% of monofunctional monomer units and 0.3-2 mass% of multifunctional monomer units and having a weight-average particle size of 1-25μm, and a vinylidene fluoride polymer (C), where the contents of the methacrylic polymer (A), the polymer particle (B) and the vinylidene fluoride polymer (C) are 40-90 pts. mass, 20-5 pts. mass, and 40-5 pts. mass, respectively. The laminated resin plate (G) comprises a substrate layer (E) comprising a methyl methacrylate resin or the like and having a thickness of 0.5-5 mm, and laminated on one surface or both surfaces thereof, a surface layer (F) comprising the resin composition (D) and having a thickness of 10-500μm, hardly suffers from deformation and has an excellent surface hardness.
