Abstract
The polylactic acid composite material of the present invention comprises a polylactic acid, a low molecular weight compound which has an amide group, and a layered clay mineral that is organically modified by means of an organic onium salt. As a result, a polylactic acid composite material that has a sufficiently rapid crystallization rate, and that is superior in terms of heat resistance, moldability and mold release characteristics can be obtained.
