    • PROBLEM TO BE SOLVED: To provide a polylactic acid resin usable in place of ABS resin or the like in an application wherein high heat conductivity and high impact resistance are required, and having impact resistance comparable to that of ABS resin or the like, having excellent flexibility against bending break strain and tensile break strain, and producing a molded article having bleeding resistance in a simple manner; and a composition using the same; a molded article; and a process for producing the same. SOLUTION: This polylactic acid resin composition includes a polylactic acid resin and carbon fibers, wherein the polylactic acid resin includes a segment of polylactic acid compounds and a segment of amino-containing polysiloxane compounds having amino groups in side chains thereof, the amino group is contained in an average amount of 0.01-2.5 mass% based on the amino-containing polysiloxane compound and 3-300 ppm by mass based on the polylactic acid compound.
