Patent ID: 8431212

Claim:
A laminate sheet of polylactic acid-based resin comprising Layer A and Layer B consisting of polylactic acid-based resin composition and both of said Layer A and said Layer B contain a nucleating agent, and said Layer A and said Layer B satisfy the following conditions (1) and (2): 0<Xb<Xa (1) wherein, Xa: containing ratio of the nucleating agent with respect to the whole polylactic acid-based resin composition constituting said Layer A (by mass %) Xb: containing ratio of the nucleating agent with respect to the whole polylactic acid-based resin composition constituting said Layer B (by mass %) Da<Db, 1.2≦Db≦10 (2) wherein, a relation of a containing ratio Da (mol %) of D-lactic acid unit in the polylactic acid-based resin constituting said Layer A and a containing ratio of D-lactic acid unit Db (mol %) in the polylactic acid-based resin constituting said Layer B is Da<Db.
