PURPOSE: A fuel tank for a vehicle using alcohol fuel is provided to maintain the component ratio of alcohol fuel in a fuel tank to be in a small allowable error since in the process of injecting alcohol fuel into a fuel tank, the remaining alcohol fuel and the newly injected alcohol fuel are mixed at a proper ratio. CONSTITUTION: A fuel tank(100) for a vehicle using alcohol fuel comprises a main fuel tank(101), a secondary fuel tank(102), a fuel inlet(110), a fuel transfer pipe(120), and an orifice(130). The secondary fuel tank is spaced from the main fuel tank and is communicated through a connecting channel(104). The fuel inlet passes through one wall of the main fuel tank and one end faces the inside of the main fuel tank. The fuel transfer pipe connects the secondary fuel tank and the fuel inlet. The orifice is attached to the inner surface of the fuel inlet and has a streamline shape. If the fuel is injected from the outside through the fuel inlet, the remaining alcohol fuel of the secondary fuel tank is sprayed and mixed in vicinity of the orifice in the fuel inlet and is transferred to the main fuel tank.
