description Provided are a glass fiber reinforced polypropylene resin pellet which undergoes little of mechanical strength lowering under circumstances of contact with metal and a vehicle front structure obtained from the resin pellet. A glass fiber reinforced polypropylene resin pellet comprising polypropylene resin (A), glass fiber (B), heavy metal deactivator (C), phenol-based antioxidant (D), sulfur-containing antioxidant (E), hindered amine-based light stabilizer (F), phosphorus-containing antioxidant (G) and ultraviolet absorber (H), wherein, as regards the weight of the respective components, the ratios (A)/(B), (C)/[(A)+(B)], (D)/[(A)+(B)], (E)/(D), (F)/(D), (G)/(D) and (H)/(D) are each in their respective specific ranges, the component (B) is arranged in parallel to one another with a length approximately equal to a pellet length, the pellet length is in a specific range, and an intrinsic viscosity of the component (A) is in a specific range, and a vehicle front structure obtained from the pellet.
