PROBLEM TO BE SOLVED: To provide a multilayer resin sheet and a vending machine display using it. SOLUTION: This multilayer resin sheet is obtained by laminating a copolyester resin layer comprising 100 pts.mol terephthalic acid unit, 80-60 pts.mol ethylene glycol unit and 20-40 pts.mol spiroglycol unit on both sides of a polyethylene terephthalate-based resin layer (core layer), in which (1) one surface is mirror finished, (2) the other surface is an embossed surface with average surface roughness value Ra of 0.3-2μm and (3) the thickness of the core layer accounts for 20-70% in the total thickness. The multilayer resin sheet can be suitably used for an advertising display board with a backlight or a dummy display in a vending machine since it is excellent in continuous printability, good in thermoformability, good in adhesion of printing ink, good in thermal resistance and good in thermal processability.
