To provide a bullet made of a resin composite material of high specific gravity, having high specific gravity similar to lead without using harmful substances such as lead, having plastic deformability, and easy in adjusting its specific gravity.

This bullet made of the resin composite material of high specific gravity has a composition including a thermoplastic resin of a glass transition temperature (Tg) of -15°C or lower by 2.0-4.0 mass%, a thermosetting resin by 0.3-1.0 mass%, and tungsten power and/or tungsten alloy power, and unavoidable impurities for the rest, and has a specific gravity of 9-13. At least one or more kinds of additives of bismuth, copper, nickel, cobalt, iron, manganese, tin, chrome and zinc are included by 3-15 mass% in total, and a composition including tungsten powder and/or tungsten alloy powder, and unavoidable impurities is included as the rest of the thermoplastic resin and thermosetting resin, including the additives.
