<P>PROBLEM TO BE SOLVED: To provide a molded article which is low in the degree of dependence on petroleum products, and is excellent in surface appearance in addition to heat resistance, impact resistance and durability. <P>SOLUTION: The molded article is obtained by molding a resin composition including a polylactic acid resin (A) and a polycarbonate resin (B), and having a mass ratio (A/B) of the polylactic acid resin (A) to the polycarbonate resin (B) of 40/60 to 80/20 and a ratio (MFR<SB POS="POST">A</SB>/MFR<SB POS="POST">B</SB>) of the melt flow rate of the polylactic acid resin (A) (MFR<SB POS="POST">A</SB>) to that of the polycarbonate resin (B) (MFR<SB POS="POST">B</SB>) at 240°C, 21.2N load of 20-600. Particles of the polycarbonate resin (B) are dispersed in the polylactic acid resin (A) in a range from the surface of the molded article to a depth 5 μm, and the length of dispersed particle cross sections observed in a cross section of the molded article is 0.1 μm or more. <P>COPYRIGHT: (C)2013,JPO&INPIT |
