Abstract

The polylactic acid-based resin composition includes (a) (i) 100 parts by weight of a poly-L-lactic acid; or (ii) 100 parts by weight of a poly-DL-lactic acid comprising L-lactic acid and D-lactic acid as its constituting units; and (b) 5 to 120 parts by weight of at least one of low-molecular lactic acid derivatives. The molded product is produced by the steps of 1) melt-kneading (a) one of the above components (i) or (ii) and the component (b); and 2) subjecting the melt-kneaded product obtained in step 1) to an injection molding, to give a desired molded product.
