A stretch mold container of the present invention is obtained by draw-forming a resin composition containing a poly-L-lactic acid (A) and a poly-D-lactic acid (B) at a molar ratio A:B in a range of 95:5 to 60:40, and has an amount of heat shrinkage of 5.0% or less under heat treatment conditions of 65° C.×24 hours. Despite of being made from the polylactic acids, the stretch mold container exhibits excellent heat resistance.
