Abstract
Disclosed is a resin composition including a polylactic acid resin (A) and a polycarbonate resin (B) and a molded article produced by molding the resin composition. The mass ratio (A/B) between the resins (A) and (B) is 40/60 to 80/20. The ratio (MFRA/MFRB) between the melt flow rate (MFRA) of the polylactic acid resin (A) and the melt flow rate (MFRB) of the polycarbonate resin (B) at 240° C. under a load of 21.2 N is 20 to 600. The polycarbonate resin (B) is particle-dispersed in island shapes in the polylactic acid resin (A) in a range from a surface of the molded article to a depth of 5 μm and lengths of cross sections of dispersed particles observed in a cross section of the molded article are 0.1 μm or more.
