A method for producing an injection-molded article of a poly lactic acid resin composition, including filling a melt-kneaded product of a polylactic acid resin composition containing a polylactic acid resin, a plasticizer containing a polyoxyalkylene group or an oxyalkylene group, and a mold releasing agent having a melting point of from 20° to 75°C in an injection-molding machine to mold in a die, wherein the method is characterized in that the above-mentioned injection-molding machine comprises a cylinder at least a part of which has a set temperature of 200°C or higher, that the die has a surface temperature of 85°C or higher, and that the die has a surface roughness of 1.0 µm or less. Since the molded article obtained by the method of the present invention has high productivity, and further excellent surface external appearance, the molded article can be used in various industrial applications such as daily sundries, household electric appliance parts, packaging materials for household electric appliance parts, and automobile parts. |
