PROBLEM TO BE SOLVED: To provide a thermoplastic resin sheet which reduces drawdown on heating in vacuum molding, excels in vacuum moldability, and has a good diffusion reflectance. SOLUTION: The thermoplastic resin sheet includes 60-80 mass% ethylene propylene block copolymer (A) having a melt flow rate at 190°C of 0.3-1.0 g/10 min and 20-40 mass% high density polyethylene (B) having a melt flow rate at 190°C of 0.1-1.0 g/10 min and includes 5-10 mass% titanium oxide (C), based on the total mass of the components (A) and (B). Preferably, the surface of the resin sheet is embossed. COPYRIGHT: (C)2011,JPO&INPIT
