Zusammenfassung:A method for producing an injection-molded article of a polylactic 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.
