PROBLEM TO BE SOLVED: To improve heat resistance and crystallinity of a polylactic acid resin and improve moldability of a stereo complex by partially forming the stereo complex in the polylactic acid resin and industrially readily obtain a highly heat-resistant and high-modulus molded product which has been impossible in a conventional polylactic acid thereby. SOLUTION: The polylactic acid resin composition comprises 2.5-10.0 wt.% poly-D-lactic acid mainly composed of D-lactic acid and 90.0-97.5 wt.% poly-L-lactic acid mainly composed of L-lactic acid, wherein the part forms the stereo complex and the resin composition has at least 4% breaking elongation.
