Abstract: In a resin composite, polyolefine grains are dispersed in a polyamide matrix. Each of the polyolefine grains has a core made of an unmodified polyolefine and a shell made of another polyolefine that is modified. In one embodiment, the core is made of a crystalline polypropylene resin (C), and the shell is made of modified copolymer (B) having ethylene units and .alpha.-olefine units. The modified copolymer (B) may have the .alpha.-olefine units as a major component. The resin composite has 30 to 80 percents by weight of polyamide (A), 1 to 30 percents by weight of the modified copolymer (B), and 19 to 69 percents by weight of the crystalline polypropylene resin (C) wherein the sum of the polyamide, the modified copolymer, and the crystalline propylene resin is 100 percents by weight. In another embodiment, the core is made of an unmodified copolymer (E) having ethylene units and .alpha.-olefine units, and the shell is made of a modified crystalline polypropylene resin (D).
