A nylon-based resin composite material, and a pellet obtained by extruding the composite material are provided to lower water absorption and to improve bending characteristics and impact resistance. A nylon-based resin composite material comprises 100 parts by weight of a base resin which comprises 20-80 wt% of a modified nylon-based thermoplastic resin containing a benzene ring at a main chain, and 20-80 wt% of a reinforcing fiber having an aspect ratio of cross-section of 1.5 or more; and 1-30 parts by weight of at least one kind of impact modifier selected from a reactive olefin-based copolymer and a core-shell copolymer. Preferably the modified nylon-based thermoplastic resin has an intrinsic viscosity of 0.7-0.9 dl/g and an average molecular weight of 10,000-100,000.
