PROBLEM TO BE SOLVED: To provide a transparent resin composition excellent in transparency, surface hardness and impact strength, and to provide various molded products using the composition. SOLUTION: The transparent resin composition excellent in surface hardness comprises 60-87 pts.wt polymethylmethacrylate resin (A), 3-10 pts.wt. graft polymer (B) obtained by graft polymerization of (total) 40-95 pts.wt. monomer mixture comprising 60-80 wt.% (meth)acrylate, 40-20 wt.% styrene and 0-20 wt.% copolymerizable other monomer in the presence of 5-60 pts.wt. rubber-like polymer having 0.5-0.8μm volume-average particle diameter and comprising 3-10 wt.% styrene and 97-90 wt.% butadiene, and 10-37 pts.wt. copolymer (C) comprising 15-23 pts.wt. vinyl cyanide and 85-77 pts.wt. styrene (total of A+B+C is 100 pts.wt.), wherein total light transmittance of a resin molded product (3 mm thickness) thereof is≥80% and pencil hardness (JIS K-5400) is≥F.
