An object of the present invention is to provide a polylactic acid composition having a high degree of stereoification and excellent transparency, hue and wet heat stability. The present invention provides a polylactic acid (B) containing a D-lactic acid unit as a main component and a copolymer unit other than D-lactic acid in an amount of 0 to 10 mol%, and an L-lactic acid unit as a main component. Polylactic acid (C) containing 0-10 mol% of copolymer units other than the above, and the weight ratio (B / C) of polylactic acid (B) to polylactic acid (C) is from 10/90 to 90/10 And A) Stereoization degree (S) is 80% or more, B) Wet heat stability is 80% or more, C) Color difference b * value is 15 or less, D) Lactide content of 1000 ppm or less, Is a polylactic acid composition.
