PURPOSE: A device for warning of a failure of a booster is provided to warn a driver of the failure of the booster by sensing the degree of vacuum. CONSTITUTION: A device for warning of a failure of a booster includes a booster pressure-sensing unit(10) to detect the degree of vacuum of the booster; a display device(40) to let a driver know the failure of the booster; a driving unit(30) to drive the display device; and a control unit(20). The control unit compares the degree of vacuum sensed through the booster pressure-sensing unit with the predetermined reference degree of vacuum, to decide the failure of the booster, and lets the driver know the failure of the booster through the display device by controlling the driving unit.
