PROBLEM TO BE SOLVED: To provide a resin composition excellent in characteristics such as moldability and heat resistance. ! SOLUTION: The resin composition is obtained by blending 100 pts. wt. of a polylactic acid resin (A) having the D form content lower than 0.5% or higher than 99.5%, 0.1-30 pts. wt. of a crystal nucleating agent (B) and 1-10 pts. wt. of a plasticizer (C). A temperature difference (Tc-Tcc) between the temperature-rise crystallization temperature (Tcc) of the polylactic acid resin (A), which has the D form content lower than 0.5% or higher than 99.5%, and the temperature-falling crystallization temperature (Tc) thereof is set within 10-20°C when measured by using a differential scanning calorimeter (DSC). !
