Abstract
A polylactic resin composition, including: polylactic resin as main component, wherein in a binary image of the polylactic resin composition obtained by binarizing a phase image of a cross-section of the polylactic resin composition observed with an AFM in tapping mode based on intermediate value between maximum and minimum values of phase differences of the polylactic resin composition in free vibration, phases equal to or greater than intermediate value are dispersed in a phase less than intermediate value, and average equivalent circle diameter of the phases equal to or greater than intermediate value is from 0.2 μm to 1 μm, and wherein polylactic resin composition is detected to have at least one glass transition temperature (Tg) in a range of −20° C. or lower, and at least one glass transition temperature (Tg) in a range of 40° C. to 70° C. in a temperature elevating process of differential scanning calorimeter (DSC) measurement thereof.
