Zusammenfassung:	PURPOSE:To obtain a resin composition, excellent in molding processability, especially pellet biting in properties and mold releasability in injection molding and useful for producing parts of thin-walled or complicated shapes by adding and blending a thermoplastic polyester resin with a specific fatty acid ester. CONSTITUTION:A polyester resin composition is obtained by adding and blending (B) 0.01-10 pts.wt., preferably 0.1-2 pts. wt. fatty acid ester, composed of (B1) a polyhydric alcohol selected from glycerol and pentaerythritol, preferably the pentaerythritol and (B2) a fatty acid ester composed of a >=12C, preferably 16-22C fatty acid (e.g. glycerol monostearate), most preferably stearic acid or behenic acid and having >=100 and
