An object of the present invention is to provide an aid for filler-reinforced resins, a filler-reinforced resin composition comprising the aid for filler-reinforced resins, and a molded article formed from the filler-reinforced resin composition. The above aid for filler-reinforced resins is capable of improving reinforcing properties and dispersibility of the filler in the filler-reinforced resin composition, and when the filler-reinforced resin composition is formed into a molded article, the aid for filler-reinforced resins enables the molded article to have superior mechanical characteristics, such as an impact resistance and a flexural strength. The present invention provides an aid (C) for filler-reinforced resins which is a modified polyolefin obtained by a reaction between a polyolefin resin (A) having a group reactive with a carbodiimide group and a compound (B) having a carbodiimide group, in which the content of the carbodiimide group to 100 g of the modified polyolefin is 1 to 200 mmol; a filler-reinforced resin composition comprising the aid (C) for filler-reinforced resins, a polypropylene-based resin (F), and a filler (G); and a molded article formed by molding the resin composition.
