Abstract
A polylactic acid resin composition includes: 0.005 parts by weight to 1.2 parts by weight of a metal phosphate represented by Formula (1):MHPO  (1)(in Formula (1), M is an alkali metal atom or an alkaline earth metal atom, and x, y, and z are integers satisfying 1≦x≦2, 1≦y≦4, and 2≦z≦8, respectively) with respect to 100 parts by weight of a polylactic acid resin including a poly-L-lactic acid component and a poly-D-lactic acid component, wherein a crystallization enthalpy of crystals in the polylactic acid resin is not less than 5 J/g when a temperature of the polylactic acid resin composition is increased to 250° C., and the temperature is kept constant for 3 minutes, followed by decreasing the temperature at a cooling rate of 20° C./min in differential scanning calorimetry.
