PROBLEM TO BE SOLVED: To provide a polylactic acid-based resin-laminated sheet excellent in heat resistance, impact resistance and a high biomass degree. SOLUTION: The polylactic acid-based resin-laminated sheet comprises layers A, B and C consisting of a poly(meth)acrylate-based resin and a polylactic acid-based resin composition. The layers A, B and C satisfy the conditions: 7≥Xa(PLA)≥0; 30≥Xb(PLA)≥10; and 100≥Xc(PLA)≥95. The layers A, B and C are sequentially superposed in the order of the layers A, B, C, B and A. In the conditions, Xa(PLA) represents the content (wt.%) of a polylactic acid-based resin based on the total amount (weight) of the acrylate-based resin and the polylactic acid-based resin, constituting the layer A; Xb(PLA) represents the content (wt.%) of a polylactic acid-based resin based on the total amount (weight) of the acrylate-based resin and the polylactic acid-based resin, constituting the layer B; and Xc(PLA) represents the content (wt.%) of a polylactic acid-based resin based on the total amount (weight) of the acrylate-based resin and the polylactic acid-based resin, constituting the layer C.
