PROBLEM TO BE SOLVED: To provide a fuel tank that can reduce the waste consumption of liquid fuel. SOLUTION: A plurality of tubular members 41 of the fuel tank 1 are raised inside a tank main body 2 via mounting brackets 43, 43 with a bottom end 41b separated from an inner bottom surface 24 of the tank main body 2. In each of the tubular members 41, a float 46 is fitted into the inside 44. The specific gravity of each float 46 is set to be smaller than that of liquid fuel A, is formed into a cylindrical shape in accordance with the shape of the inside 44 of the tubular member 41, and is fitted into the inside 44 with its circumferential surface 48 slidably in contact with the inner circumferential surface 49. The circumferential surface 48 of the float 46 slides on the inner circumferential surface 49 of the tubular member 41 is a state of the float 46 fitted in the inside 44 of the tubular member 41, which allows the float 46 to move in the vertical direction E in the inside 44 of the tubular member 41 and which prevents the float from being fallen.
