PROBLEM TO BE SOLVED: To attain improvement of balance of impact strength, heat-resistance, processability and uniformness of appearance of a thermoplastic resin composition containing a poly-lactic acid resin. SOLUTION: The thermoplastic resin composition comprises 5-60 pts.wt. of the poly-lactic acid resin (L), 10-70 pts.wt. of a rubber-containing graft copolymer (G), 5-50 pts.wt. of a polycarbonate resin (C) and 10-80 pts.wt. of anα-methylstyrene-acrylonitrile copolymer (A) (provided that total of (L), (G), (C) and (A) is 100 pts.wt.). 70 wt.% or more of a monomer used for graft polymerization of the rubber-containing graft copolymer (G) is a (meth)acrylate based monomer.
