A draw-molded and heat-set article obtained by draw-molding and heat-setting a hydroxyalkanoate resin comprising chiefly a polylactic acid, the draw-molded and heat-set article having a half-width (X) of a diffraction peak of 2theta=10 to 25° of not larger than 1.220° and, particularly, not larger than 1.100° as found by a broad-angle X-ray measurement. The molded article possesses excellent transparency and heat resistance despite it is made of a spontaneously integrating plastic material. The draw-molded article and, particularly, a container is effectively used for containing beverages.
