An object of the present invention is to provide a polylactic acid-based stretched material excellent in ductility, strength, and transparency, and a method for producing the same, comprising a plant-derived biodegradable material, polylactic acid as a main component. A polylactic acid material comprising 60 to 99% by weight of polylactic acid (A) and 40 to 1% by weight of a copolymer having a functional group reactive with the polylactic acid (B). .
