Claim:
A polylactic acid-based resin sheet comprising polylactic acid and rubber particles having a ratio X/Y of more than 0 and 1 or less, where X and Y represent a number of primary particles and agglomerates, respectively, and characterized by satisfying (1) to (3): 0.01 Î¼mâ‰¦| Ra 1âˆ’ Ra 2|â‰¦0.2 Î¼mâ€ƒâ€ƒ(1) Ra 1â‰¦0.3 Î¼mâ€ƒâ€ƒ(2) Ra 2â‰¦0.3 Î¼mâ€ƒâ€ƒ(3) where Ra1 is a two-dimensional center line average roughness of one surface of the sheet, and Ra2 is a two-dimensional center line average roughness of a surface other than that subjected to measurement of Ra1.
