PURPOSE: A warning device of fuel leakage is provided to warning a driver of the fuel leakage by installing several pressure sensors in a fuel tank. CONSTITUTION: A warning device comprises: several pressure sensors(100a, 100b) to sense the pressure change in a fuel tank; an amplifier(120) to amplify the sensed signal; a comparer(140) to include the amplified signal and the signal passed through a timer(130); a bell operating part(150) to check the pressure change and to operate a warning lamp(160) and a bell(170); the warning lamp and the bell to be controlled by the bell operating.
