Biaxially formed by stretching a composition containing a styrene-methacrylic acid-methyl methacrylate copolymer resin, which has excellent heat resistance, appearance and mechanical strength, and also has good blocking resistance of sheets and molded products. To provide a stretched styrene resin sheet and a molded product thereof. A styrene-methacrylic acid-methyl methacrylate copolymer resin (A) obtained by copolymerizing styrene, methacrylic acid and methyl methacrylate, an impact-resistant styrene resin (B), and an average particle size of 1 to 20 μm. A composition containing an inorganic granular material, wherein a mass ratio (A) / (B) between the resin (A) and the resin (B) is (98 to 99.7) / (2.0 to 0.3) and using a styrenic resin composition in which the mass ratio of the inorganic particles in the composition is in the range of 50 to 500 ppm, the draw ratio in the transverse direction and the longitudinal direction is 1. A biaxially stretched styrene resin sheet formed by biaxial stretching in the range of 8 to 3.5 times. [Selection figure] None |
