PROBLEM TO BE SOLVED: To provide a polylactic acid laminated sheet having sufficient impact resistance, heat resistance and thermal bending formability without particularly increasing a sheet thickness and a tough thermally bent formed object made from the sheet withstanding distribution or storage. SOLUTION: In the polylactic acid laminated sheet having a layer A based on a polylactic acid polymer and stretched and fixed under heating and a layer B based on a polylactic acid polymer having a melting point lower than that of the polylactic acid polymer constituting the layer A, a predetermined relation is satisfied when the melting point of the layer A is set to Tma(°C) and the melting point of the layer B is set to Tmb(°C).
