PROBLEM TO BE SOLVED: To provide a fiber-reinforced polylactic acid-containing resin composition forming a molded body having excellent balance of properties, such as flexural modulus and impact strength, and improving product performance, and applications thereof. SOLUTION: The fiber-reinforced polylactic acid-containing resin composition includes a component (A): a polypropylene-based resin, a component (B): a polylactic acid-based resin, a component (C): organic fibers, a component (D): an acid-modified polyolefin-based resin or/and a hydroxy-modified polyolefin-based resin, a component (E): an epoxy-modified polyolefin-based resin, and, if needed, a component (H): a propylene-based polymer, and is produced through the following steps (I) to (IV). The step (I): performing melt kneading of the component (B) and the component (E); the step (II): performing melt kneading of the composition obtained from the step (I), a part of the component (A), and the component (D); the step (III): producing a composition including the residue of the component (A) and the component (C) separately from the step (II); and the step (IV): performing mixing or melt kneading of the composition obtained from the step (II), the composition obtained from the step (III), and, if needed, the component (H).
