摘要

[Object] It is an object of the present invention to provide a resin composition having improved heat resistance (high crystallinity) and transparency without impairing rigidity intrinsic to a polylactic acid based resin, a molded body formed from the resin composition, and a new polylactic acid based resin used in the resin composition. A polylactic acid based resin (A) according to the present invention is characterized by having a specific structural moiety and a weight average molecular weight (Mw) of 5,000 to 1,000,000. A polylactic acid based resin composition according to the present invention is characterized by containing the above-described polylactic acid based resin (A).
