摘要： A fiber-reinforced polypropylene-based resin composition is disclosed that includes a polypropylene-based resin (A); an unsaturated carboxylic acid-modified polypropylene-based resin (B) in which the amount of a polypropylene-derived C24 or lower oligomer component that volatilizes when heated at 150° C. for 30 minutes is less than 200 μg/g; and reinforcing fibers (C). Also disclosed is a method for producing the fiber-reinforced polypropylene-based resin composition described above. The method includes a step of obtaining the unsaturated carboxylic acid-modified polypropylene-based resin (B) by kneading a polypropylene, and an unsaturated carboxylic acid or a derivative thereof together with an organic peroxide at 170 to 200° C.
