[PROBLEMS] To provide excellent heat resistance, impact resistance, sufficient strength when subjected to a load at high temperatures, no wrinkle-like defects called “bridges”, and deep-drawn molded products and shapes. An object of the present invention is to provide a biodegradable laminated sheet having good moldability of complicated blisters. The laminated sheet comprises at least two layers, and each layer constituting the laminated sheet has a polylactic acid resin of 75 to 25% by mass, a glass transition temperature of 0 ° C. or lower, and a melting point of the polylactic acid resin. Consists of a resin composition in which polyester resin 25 to 75% by mass, which is higher than the glass transition temperature of the resin and not higher than the melting point of polylactic acid resin, is blended so as to be 100% by mass in total, and constitutes the laminated sheet The D-lactic acid content of the polylactic acid resin contained in one layer and the D-lactic acid content of the polylactic acid resin contained in the other layer constituting the laminated sheet have a predetermined relationship. Furthermore, a biodegradable laminated sheet that has been crystallized is used as the laminated sheet. [Selection figure] None |
