Abstract: The invention is to provide a flame-retardant polypropylene resin composition that exhibits extremely high-level flame retardance and is given mechanical properties (rigidity, impact shock), weather resistance and moldability by satisfying both self-extinguishing property and drip resistance and to provide a molded article using the composition. The invention relates to a polypropylene resin composition comprising a specific polypropylene resin (A) that contains a polypropylene resin (X) having a specific long-chain branched structure, a specific fiber (B) and an organic flame retardant (C) each in an amount falling within a range of a specific amount, and to a molded article obtained by molding the composition.
