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 an injection-molded body. 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, and a component (E): an epoxy-modified polyolefin-based resin. The content of each component is preferably, based on the total resin composition, 7-91.4 wt.% of the component (A), 4-40 wt.% of the component (B), 4-40 wt.% of the component (C), 0.1-3 wt.% of the component (D), and 0.5-10 wt.% of the component (E). Preferably, production is performed by a step (I) of performing melt kneading of the component (B) and the component (E), and a step (II) of performing melt kneading of the composition obtained from the step (I), the component (A), the component (C), and the component (D) at a temperature not causing plasticization of the component (C).
